I'm "left handed" when i write, draw, ect.. anything with a pencil pretty much, however when it comes to every thing else i can use either hand. I have no clue where i picked it up at because i couldn't use my right hand for any activity such as sports, eating, ect..., for the first 9 or 10 years of my life. Then came my 11 B-day and i started to use both of them i don't know why, but yeah i do have problems like that also. I can't tie-shoes at all any more i pretty much just pull them tight and shove them into my sock's or shoes, and to make things worse i have a shaking problem thats not stress related or some abnormality ( at least one a doctor can find), but i just shake all the time my whole body is always either shaking or moving i can't make it stop either, so it's quite funny to see me do pull-ups, it looks like im having a seisure . Your not alone my friend, your not alone.
