Benefits of Using Your Opposite Hand – Grow Brain Cells While Brushing Your Teeth

How to Grow Brain Cells While Brushing your Teeth


As I get older, it seems that I’m constantly getting these nagging injuries from me doing my crazy Crossfit workouts. (You can ask the wife, she’s tired of hearing me complain).

I’ve tweaked my shoulder, left knee, right trap (upper back), forearm, and; most recently, my right bicep.

I had never hurt my bicep that much before and was surprised on how much it affected my day to day activities.

It affected them so much that I had to rely on my left arm to pick up the slack.

The incident had reminded me about some show that I watched that discussed on how much of a benefit it was to use your non-dominant hand.

You may be surprised to learn that there are benefits to you when using your opposite hand – I know I was.

It feels awkward and you are likely to have much less control over what your non-dominant hand can do, but when you use your opposite hand you are “growing” your brain! I used my injury as a chance to permanently grow my brain for ever more.

I made a vow to start using my left hand for as many tasks that were previously always done with my right. It was time to grown my brain. Trust me. I need all the help I can get. :)

This is Your Brain

The human brain is an organ that improves through mental stimulation. The brain continuously adapts, grows and rewires itself through the growth of new neurons. When people age, it’s common that they experience memory loss and sometimes their fine motor skills – but unless the mental decline is caused by disease, most age-related memory and motor skill ability loss is from lack of brain exercise. If you don’t use your brain, it loses it’s knowledge.

This is Your Brain Left Handed

Using your opposite hand will strengthen neural connections in your brain, and even grow new ones. It’s similar to how physical exercise improves your body’s functioning and grows muscles.

Try using your non-dominant hand to write. Use it to control the computer mouse or television remote. Brush your teeth with your other hand. You’ll probably notice it’s much harder to be precise with your movements. When I first started to brush my teeth with my left hand, it was hard to actually move my hand instead of my head.

benefits of using nondominant hand

Now let’s see how I write with my left hand….

Using your left hand might remind you how you felt when you were first learning to write your name, or tie your shoelaces. You will probably feel awkward, but this just means you are teaching your brain a new skill.

Repetitively using your opposite hand will eventually build up the knowledge and ability to use it with better functioning, although it’s probably not going to become as easy to use as your dominant hand.

Your Opposite Hand – Unleashes Creativity

Using your non-dominant, or opposite hand, confuses your brain. The brain is in charge of keeping you functioning and it does that with predictability.

It understands the way our bodies work and behaves in the world, but when we try writing with our opposite hand – it confuses the brain and it’s efficiency.

The brain that operates effectively for our every day activities may not be the same parts of the brain which allows us to be creative.

If you’d like to unleash some hidden creativity, try writing with your opposite hand. As bad as my penmanship is, writing with my left hand isn’t really that worse :) It is sometimes the nudge our practical brain needs to “move out of the way” for the creative juices to get flowing again!

The non-dominant hand is actually linked to the non-dominant hemisphere in your brain – the one that isn’t exercised as often. There are studies that show that when you use your dominant hand, one hemisphere of the brain is active. When you use the non-dominant hand, both hemispheres are activated, which may result in thinking differently and becoming more creative.

What I Now Do With My Left Hand

I was amazed on how challenging it was in the beginning to use my left hand. I felt like a doofus and realized how uncoordinated my left hand really is.

Now, I consciously make an effort to use my left hand as much as I can. Here’s some the day to day activities that I’ve been able to successfully convert to southpaw:

benefits of using your non domiant hand for brain function

Do my teeth cleaner using my left hand?

  • Brushing my teeth
  • Pouring Drinks Milk/Water from Brita Pitcher/My health shake from blender. (I’m amazed on how messy I was pouring my health shake out of a blender)
  • Opening jars
  • Scooping protein powder/baby formula
  • Washing my body
  • Cleaning dishes
  • Occasionally using a my computer mouse (I’m seriously considering buying a left handed mouse)
  • Buttering toast (try spreading peanut butter on toast. It’s a whole different world).
  • Carrying the car seat
  • Using can opener
  • Eating with chopsticks (this one is really tough)
  • Occasionally using my mouse (I’m seriously consider buying a left hand mouse for good)

Can You Benefit From Using Your Non-dominant Hand?

Some therapists have used an exercise where they ask their patients to write with their opposite hands, and it allows people to access some suppressed emotions. If this interests you, contact a trained professional to help you through this activity.

For use in every day life, however, you can simply try writing with your opposite hand a little each day, asking your “every day brain” to move aside, and see if it helps you become more creative or triggers improved memory functioning.

Have you ever tried using your non-dominant hand for daily tasks? If so, share your story. Did you feel as clumsy as I did?

    I try to use my left (non-dominant) hand as much as I can, although it’s usually because I’m trying to multitask in the morning and am usually running late…i.e., gathering my stuff up for work with my left hand while I’m brushing my teeth with my right. Sometimes it works well, sometimes not so much. I often feel pretty clumsy. I am largely a righty although I do tend to carry things lefty – purses/schoolbags always tossed over my left shoulder, carrying more grocery bags with the left than right, etc.

  2. says

    Jeff dude, this is one of the most awesome posts I have read in a while.

    I love the brain, I love minty toothpaste, it was a match made in heaven. I am off to get cracking on the left handed brushing right now.

  3. says

    Fascinating post. I hadn’t given the idea much thought before but I can believe there’s a connection.

    I remember when my son was a toddler – there was definitely a correlation between physical activity and intellectual & linguistic development.

    And I also recall a study in the past involving strokes. Researchers found that by immobilizing the unaffected arm/hand of a stroke victim so that it couldn’t be used, the stroke victim experienced better and quicker recover on the affected side.

    Fascinating stuff.

  4. Cyndi says

    The thought of being forced to use my left hand for ever purpose, need and task was nerve wrecking. After just a week the tasks-still awkward-were becoming more normal. Daily things like brushung my teeth, buttons on clothing, texting, eating were becoming familiar and even to the point were it was becoming normal. I now at times think what will it be like when my cast comes off I can use my right hand again.

  5. J.Antony Peter Selvam Silva says

    Today I have started using by Left Hand. Is it true that using non-dominant(Left Hand) will increase IQ Power. Please Reply

  6. Julie says

    Good read. This is great in theory but really hard in practice. Some other “off the wall” tactics I have tried is listening to classical music while studying and listening to audio notes I needed to learn for a class on my ipod while sleeping. Only problem with that is the earbuds do not tend to stay in place!

  7. says

    I’ve tried it for brief stints, but never stuck with it for long. I’ve heard the theory of non-dominant hand use helping to develop brain power more than once now, so I think I’m going to try it. In the meantime, I’m trying to find ways to use other fingers for the job my index finger usually does. Not having a lot of luck so far. Great post.

  8. Amit says

    Good one. Tried a few things , found it difficult…
    But surely will keep on trying as I think it will improve my overall workings.

  9. Brianna says

    I used chopsticks with my left for the first time today. It wasnt hard at all. I can’t use my right correctly with them though. :p

  10. charleigh.cassidy says

    I doing the left-handed mouse maneuver at this very moment.
    Well, not this moment because I am typing.
    A couple times I caught myself leaning over my keyboard to let my right hand move the mouse because my everyday brain thinks: right hand=mouse.
    I like this. It does feel a bit awkward, but it’s not too hard to get used too. I have at least seven more hours on my shift so I will see if I get tired of the southpaw mouse action and switch back to the right hand.
    I doubt it though. I’m interested in the effects the use of the non-dominant hand will have on my noggin.
    The most prominent issue I have is using the scroll wheel. I’m just not accustomed to moving my left hand in that way. I cheat and use the page up, page down buttons next to the keypad… It’s easier—but I won’t give up training my non-dom to work the wheel.

    Your post was fun to read.
    Many thanks

  11. Mike says

    I am considered left-handed. While recovering from hand surgery for 6 weeks I was forced to write/print right-handed. It was never comfortable, but legibility did increase between start and end. I quickly reverted back to left-hand writing when the cast came off. As fart as using a mouse, either side is fine though I usually leave it on the right as I have a shared computer.
    While I am a leftie, I do several things rightie! Using a wrench ‘feels’ better in my right hand. Also, I play (at least make noise) guitar as a rightie. I tried guitar with switched strings and it never ‘felt’ right.
    I kick right-footed, throw left, catch right.

  12. John D. says

    You don’t have to buy a lefty mouse. You can reconfigure it with the control panel. Unless this was originally writtin in the 90s :P I am doing this same thing. The only things I was truly right dominate in is writing and throwing. EVERYthing, I’m naturally both, thank god lol. It’s only been a week of lefty writing and it’s made a drastic improvment. I thinking throwing will be quicker, though. Hopefully this won’t take too long :P

  13. juhi says

    i ve been practicing writing with left hand since last december…even though i skipped a few months yet i can write pretty fluently except that the writing looks a bit edgy…now i will practice writing with both hands simultaneously..i really feels adventerous…. :) and believe me if you write/practice regularly your,, non dominant hand will act some times dominantly.

    • tom says

      Hello juhi i too started to practice to write in left hand and i started to do all the works in left hand. As a junior i would like to ask you a thing. Will it create any problem in brain or will it stimulate the right side hemisphere and the result will be good. Eagerly waiting for your reply. thanks

  14. says

    Hi Jeff,
    I’ve been doing left-handed activities for three years now. I actually played college tennis right-handed and decided to learn left-handed. So now I can play very well left-handed. It has definitely helped balance out my body and mind.

  15. Natasha says

    i have just started to use my left hand to type this email and i am already feeling great. You see i am a right hander using my right brain. i have always felt that i have poor blood circulation but at this very momment i feel like my blood is flowing like it should. I also notice that i am thinking clearly. Thanks
    From now on i am going to try to do everything with my left hands.

    • Bill says

      nn, when you use your right hand, your LEFT brain is used. When you use your left hand, your RIGHT brain is being used.

  16. Niki says

    Very interesting. I had surgery on my dominant hand, and was forced to use my left.. For writing and pretty much everything. It was tough at first but after almost a month, I haven’t stopped! I feel great! More brain power, I almost perminently write with my non dominant hand now. I will continue to use it, after I am completely healed, hopefully they will become even

  17. says

    This was an interesting read.
    I was ambidextrous as a child, but my school hated how “lazy” it made me (i.e. one hand would get tired, so I would use the other). They decided I was right handed and tried to get me to stick with it. I still do everything left handed except right and in some things, like sports, I’m better lefty. I am working at it and hope to be back to “normal” by the end of this year.

  18. bonni says

    Having had an operation on my right shoulder I’m having to do most things with my left(non-dominant) hand. It is difficult especially personal things. Brushing my hair is difficult as well as cleaning my teeth but things get easier the more you practice. As for making me more creative… well I can’t wait to be able to use both hands to do some experimental textile art things.

  19. says

    I’m naturally right handed. I started writing with my left hand a year ago as I was bored and reading up on left-right brain hemispheres and I came upon the term ambidextrous. So I gave it a shot, once a week I would write for 5-10 minutes the alphabet and numbers in a printing notebook. I felt like I was back in elementary school again. At first my printing was shaky, but now a year later, everyone says it looks neat and even better than their printing with their right hands :)
    I started turning switches off and on with left hand and turning door knobs, even eating soup with a spoon in my left hand. At first, it was just a joke and I would consciously have to tell myself to use my left hand.
    But a year later, my left hand dominates! I write with my left hand all the time. I use my right hand at work when I have to write fast, but I also work as a writer. So when I’m writing down my thoughts or ideas in my journal, I find writing with my left hand makes me write slower, so I give my thoughts a lot more time to write down.
    I also feel like I’m more balanced. Before when I was strictly using my right hand, I would do those left/right brain quizzes and my results stated that I was more right brained.
    Now that I use my left hand more than my right hand, I have done the same quizzes again and my left/right brain ratio is 48% (left brain) – 52% (right brain) – more balanced. I also feel it with my decision making and I don’t easily cry any more when I get emotional . Before becoming ambidextrous, I was extremely emotional and would cry at movies or if I heard a sad song on the radio (like a typical women).
    But now when I get teary, I can tell myself to hold back the tears and tell myself it’s not worth to cry over something so small.
    I think it has something to do with using my left hand more with handling things. So it sounds a bit crazy that using your left hand can make you become more level-headed, but it worked for me.

    I advise anyone who wants to pick up a new hobby and also better themselves to become ambidextrous, it starts with 10 minutes a week with writing with your left hand and just picking up objects with your non dominant hand. After a year of doing it, you’ll feel the difference. I know I do, and I will continue to be a ‘righty to who turned lefty! :)

    • Selina Kaur says

      Misshl, your comment has intrigued me! I’m writing a report on whether our handedness can be switched and how this can benefit or even disadvantage us as part of my A level studies (UK). I was wondering if perhaps you could email me some further details about your training and the methods you used along with maybe some evidence of your left hand and right hand writing now that you’ve been training your non-dominant hand after so long. I’d sincerely appreciate your help. Really want to achieve top grades on this project.

      Please do email me if you have the time. Thankyou (:

    • Lynda says

      I’m a lefty and very emotional. I don’t like “the bad” about being a lefty so I’m going to work on doing more things with my right hand- like writing this post.

  20. Martina says

    I love to play racquetball. When I injured my left shoulder last year in a bike accident (I’m left-handed), rather than give up racquetball, I began to play with my right hand. I’m an excellent player when using my dominant left hand- not so much with the right, but it allowed me to continue the exercise activity I love, and continue to gain the health benefit of playing regularly. Toughest part was to get past the ego aspect of looking like a clumsy beginner :)

  21. says

    Halfway through this I started to use my mouse with my left hand lol. I might have to do this, but I think I really use my brain with a lot of things I do. I play guitar, and I have to shred with my non-dominant hand. That’s a lot of coordination I’ve built up, and quite a bit of full brain usage. I must be getting super smart now!

  22. says

    Wow! This is really interesting. Not sure if this has anything to do with it but the most creative people I’ve met are tend to be left-handed rather than right-handed. I wonder how using the opposite hand for them would influence their creativity? Thanks for sharing!

  23. says

    This reminds me of something we did in high school art class. We still used our dominant hand, but the project was to look at our other hand and draw it…..without ever looking at the paper…or even lifting the pencil off the paper. The purpose was to concentrate on the detail of your hand. Then we did it again but were allowed to look at the paper, but as little as possible. That practice helped me draw one of my best pictures ever with incredible detail. I like the idea for using the non-dominant hand for as many things as possible too. I might have to start doing that.

  24. CowboyTech says

    I know this works, and I do it at times. However, so you’ll know – you don’t need to purchase a left-handed mouse. Move you regular mouse to the other side of the keyboard, then (depending on your operating system – assuming Windows of some flavor) go to Control Panel and find Mouse. Open the Mouse panel and find the tab at the top that enables you to change mouse settings. Click on “switch buttons” (or whatever it says) and the left mouse button will become the “right click” and the right mouse button will become the regular click. Voila! You now have a left-handed mouse. I’ve worked on computers for 45 years, so if you have a problem, give me a call or send me at email. Cowboytechcomputers dot com.

  25. Greg says

    I pratice marital arts, and when ever we do stuff that requires us to use are non-dominant side I am always amazed on how badly I do and was wondering what I could do to improve in this area when I came accross your post, it just make sense that one would need to just to more things with their non-dominant side in order to get better, thanks for the post.

    • Donna says

      Hi Greg…it does help with martial arts. I’ve had the same experience, and since I’ve been using my left hand for the past year, I noticed improvement. I prefer my left side (thought I’m right dominant), but its been a little uncoordinated. Just keep practicing both sides, it will help. Do more on the non-dom side than the dom side. You’ll see the difference.

  26. Spencer says

    I can do a lot of things with my left and found this article because the one thing I haven’t tried is chopsticks, which I think I will try now. I figure, my left hand is there, why not use it? It opens up a lot of opportunities for disc golf as well; you can throw backhand throws that fade right instead of left.

  27. Crystal says

    I’m a lefty and I’ve recently been practising in writing with my right hand. I know that each hand has been given specific job duties from my brain so the idea of teaching my right to write seems to quite a challenging yet fun thing to learn. Not to mention dead useful if anything does happen to my dominant hand, which hopefully it doesn’t.

    I am proud of being a lefty, I wouldn’t change it for the world and I know at heart that I’ll always be one. I always lean to the left a lot and the idea of learning to drive a right hand drive car is quite scary. But also very beneficial.

  28. Philip says

    Recently I aquired a delicious dose of carpal tunnel syndrome. It’s not so severe I have to get surgery, but it’s severe enough that it hurts my right hand even a little to do daily mousing activities. Worse than it’s ever been before.
    I now use my left hand for my mouse, teeth-brushing, eating, drinking, feeding my pets, pouring stuff… I was a little uncoordinated, but as this has happened before, not as much as I’d expect to be uncoordinated.
    Mousing is still inprecise, though, it’s like an up-down action on my desk rather than a left-right, but my left hand comes in at the side of the desk and my whole arm rests up there. I didn’t even change how my mouse clicks, my “left click” stayed on the left side, so I’m using the wrong finger for the right button.
    Just a week to go, and maybe I can be a righty again!

  29. Phoebe says

    I have used my right (non dominant) hand since I was young and have realised that I cannot use left handed scissors. However, I cannot pour drinks or drink using my right hand, I cannot use forks or spoons in my right hand, only knives, yet with sharp, kitchen knives, I am unable to use them with my right hand and as the ridges etc. on kitchen knives are suited to right handed people, I cannot use them with my left either.
    With computer mice, I usually use my right hand as that is what has always been available to me. However, if I want to use my left hand to control the mouse, it is just as easy for me.
    Recently I have been writing more and more with my right hand and although it is very difficult, it is still legible even if it does look like a five year old wrote it. Then again, when I was young and learning to write, I learned how to write backwards; completely mirrored text, before I learned how to properly write.
    Using your non dominant hand, for a left hander, is something most people grow up knowing how to do as most machinery and other day to to day items are made specifically for right handed people. Even pens and pencils are. So even though certain tasks are difficult, using the right hand is quite common even if the dominant hand is the left.

  30. tom says

    It’s a nice post Mr. Jeff. I am righty and started to do all my activities in left hand to stimulate my right hemishphere of brain. Just i wanna know stimulating right hemisphere by doing works in left hand will be good Or will it create any problems in future. Thanks

  31. Tanji says

    I have started playing tennis with my left arm due to a shoulder injury. I am curious what show it was on using non dominant hand that you referred to.

  32. says

    At School in the Infants that is I was forced to use my right hand and was chided for always trying to use the left.
    To this very day I still hold things with my left hand but I do not realize why I am doing it. I will always go to pick up things with the left hand without thinking.
    I have just written with my left hand for the first time since I was five years old.

  33. Keith Mahannah says

    This post reminds me of what I have been doing over the past year. I have been playing racquetball competitively since I was 15. Since it is a one armed sport like tennis I have developed some sever muscle imbalances that make me extremely uncomfortable. Enough that I have feel awkward while walking and sitting, but feel normal on the court. So I started to try to rehab myself by learning to do things with my extremely un-coordinated left hand. It was tough, but over the past year I have learned to brush my teeth (classic), use a mouse, wipe on the toilet (scariest and hardest), write a little bit, and now have learned to play racquetball left handed. I am no where near as good with my left hand at racquetball as my right, but I am determined to get there and possibly be even better. I think the only way it is going to happen is to quit using my dominant hand all together while playing. The funniest thing is when people say “oh I didn’t know your were a lefftie,” I usually don’t know how to respond. Most people (my wife) think I’m crazy for doing it, but I enjoy the challenge and what it is doing for my mind and body. Good luck to all who try, and thanks for this article letting me know I’m not the only crazy one.

    -Keith

  34. Jim says

    My first comment was to explain how to turn a “right handed” mouse into a “left handed” mouse. Now, I’ve been using my mouse with my left hand ever since. I also brush my teeth with my left hand, print with my left hand, and occasionally try to write with my left hand. It’s been an interesting endeavor, and one that seems to help me be, at the very least, more mentally balanced. I find myself willing to use my “south paw” more naturally and more often. I think this really works, although to what degree is unknown for sure. I actually enjoy using my left side as dominant frequently and will continue to do so.. Glad I gave this a shot.

    • CowboyTech says

      Not sure how this was attributed to someone named Jim, but that’s not my name… anyway the above post was from me… like that really matters, I suppose.

  35. Donna says

    I started using my left hand (non dominant) about a year ago on my computer mouse and number board for my computer at work. So, eight hours a day I’m using my non dominant hand, and I have seen great improvment in my memory. In the past, to remember a sting of numbers, even short term, was impossible. Once they had been “said” by a caller, I’d have to ask them to repeat if they were too fast or ahead of me. now I can remember those numbers long enough to finish a task and start to record the numbers. Pretty awesome.

    • Donna says

      I forgot to say that the reason I started lefty keying/mousing was due to martial arts injury in my right elbow, exasserbated by the constant repetitive motion of the mouse/number pad on my keyboard. Now I’m pain free…and I have more brain cells!

  36. Pamela Kearney says

    Because of arthritis in my right hand fingers, i decided to play online sudoku with my left. Wow – i am so much slower and it seems harder – ie i have to think more! Thats when i decided to research this and found your article. Will try and do more things with my left hand, and i know i will get faster at sudoku with left hand over time and give my brain more exercise!

  37. says

    I started writing with my left hand several years ago, partly out of desperation and partly to access more creative juices as a poet and artist. Now I write exclusively as a lefty, and people prefer reading my left-handed script as it is gentler and larger to read than my cramped, tiny right-handed writing. I find I can reach a poem with ease, if less speedily, using this supposed direct connection to my right brain through my left hand, and of course in artwork it produces amazing results, though it can be frustrating to draw quickly as a lefty and be hampered by the lack of my right hand’s precision. Two phenomena I have noticed: the first is that I have developed what I believe is pain in my left arm due to a kind of underuse/overuse syndrome, too much use of specific muscles and not enough emphasis on acquiring general strength through out my entire left arm. Finally, I am now working on writing backwards with my left hand, a task that is much easier for lefty writers than right-handed people. It can be mind- bogglingly difficult, but if you just go with the flow, as if writing for someone to read a sign written on your forehead, it can be done…And I keep telling myself, it isn’t only for the secrecy, no, but if Leonardo saw some value in mirror writing, well, then, surely there was some! It must train the brain somehow! I’d be interested to know if anyone else has tried this.

  38. Pablo says

    This is the third time I have felt this over the past 2 years probably. I get that awkward feeling almost as if I was doing things with my left hand only I am not! I am doing things like every day. Has anyone felt that before? It is as if all of a sudden my body kind of forgot everyday movements like moving a mouse. I mean, it is not as bad as actually using my left hand but kind of. It´s a bit scary. Anyone?

  39. RETheUgly says

    Bah, I can’t use chopsticks with my dominant hand either, but who knows? I haven’t had many opportunities to try it, but maybe learning to write with my non-dominant hand in 3 different ciphers (Latin Alphabet, Elian Script, and FEZ Writing) will bring me to that too!

  40. Eric says

    Only problem with developing the non-dominant side of the brain is that once you start, you can’t ever stop or else your brain muscle with get fat and sloppy. Don’t start something you don’t plan to finish your life with. Count the costs. Are you dedicated enough to make a lifetime commitment?
    (just kidding)

  41. Eric says

    Not sure non-dominant hand use is the answer? I’m thinking non-dominant side use is the key.
    Example. I’m a right-handed tennis player. I changed from a two-handed backhand to a one-handed backhand a couple years ago. So now I use my dominant hand (right) for both a one-handed forehand and a one-handed backhand. My dominant side is my right, I guess. I don’t even have to think about technique on the forehand. It comes natural or has become engrained in my brain. My non-dominant side is my left. So even though I use my dominant hand alone now for my backhand, I use my non-dominant side (left) to hit the shot. I forget daily how to hit the backhand on my non-dominant side and have to reteach myself daily with a long warmup session to get the groove going. The part of my brain used to hit the one-handed backhand is evidently not a part of my brain which stores long term information. I have a terrible short term memory and forget my tennis score if I have a tough point I’ve played out. My memory of the score gets wiped clean. I wonder if this is the same part of the brain the stores my motor skills for the one-handed backhand?

  42. Bill says

    I would like to clear up a misconception that being able to use the opposite hand almost as well as the dominant one does not mean the person is ambidextrous. True ambidexterity means EQUAL and there are only a very small percentage with this skill. I’ve been using my opposite hand for at least six months, doing almost everything left handed, including playing pickleball! It really feels like I’m thinking clearer, memory seems better, and problem solving/creativity has gotten much better. I even wear my watch on my right wrist! :)

    Hey Jeff, I also have been training my left arm for a year now (1-2 hours a day writing Russian cursive, English and Hebrew latters) all the little stuff that you mentioned like brushing your teeth, making tea, pouring sugar etc. I’m now throwing stuff like TV remotes and a computer mouse from hand to hand on auto pilot, it seems faster to do then pick the remote then point it on the TV direction and then clicking it..:D what I wanted to share with you is that you don’t need a lefty mouse, just go to mouse options switch the buttons to left instead of right, and go on try operating your mouse. I attempted it after i was already 8 months in the “training” and after just 2 weeks I mastered the mouse using my left hand. You will feel the hand hurting a little, but that passes quickly as you’re like me already “in the process” of teaching your brain(or more accurately, letting your subconscious know you mean business) “He” knows your intentions are to develop further so it will help you learn those things quicker.

    PS. I see some mental improvements as well, I become more curious of things, raised my concentration level. if I look at a shape i now can look at it from more then one angle.( you know like when you put 2 circles and some see only 2 circles but if you look closely you can see to half moons, but deeper then that…I was concentrating once on a piece of something with open eyes I could see the color purple beaming circles into the object then i could intensify it by will to make it luminous violet.

    Ok thought I’d share this, those are the changes I’ve experienced after perusing this skill.
    I would be glad to hear from you and other people, what you/they have experienced as well.

    sorry for my English I’m not native:).

    I found this very interesting. As an elementary school teacher, I have attended trainings on left and right brain dominance. I write with my left hand, but I am left eye dominant and do many things with both hands. For instance, I brush my left teeth with my right hand and brush my right teeth with my left hand. I also apply makeup to my left eye with my left hand and my right eye with my right hand. And I switch hands when I shave my legs. I can only snap my fingers with my left hand. When I worked retail, I entered the numbers on the credit card machine with my left hand because the credit card keypad is reversed from 10-key punch and it helped me to not enter the numbers incorrectly. I know I am not truly ambidextrous but I think I am still different from the average right hander. Was there a nun in my past who led me away from left-handedness? I guess I’ll never know . : .

      Interesting you should say these things. My ex-wife was a cosmetologist, and during her schooling in that field, she would roll hair on a person’s right side with her right hand, and on the left side with her left hand. She does a lot of things that way, but is predominantly right handed. When her teachers graded her work they didn’t know what to say, so they asked her to demonstrate how she rolled the person’s hair. When they saw she switched hands, and the evenness of the final appearance, they gave her an A+ for the quality of all her work. She does the same when cutting hair and a lot of people (customers) have been amazed at the results. When doing floral arrangements, she did the same thing with a very large arrangement that moved the customer so much they paid her $1500 for her work on that one arrangement!
