i think it has sumthing to do with RTS~
i am currently majoring in ergonomics and learned about this...
altho im failing miserably, but i think its cuz the hand is positioned in an unnatural way that causes pain in the long term...
mebe thats cuz u didnt feel it before and feeling it now.
and dont ask me wat RTS stands for. my gpa is 1.25
(i hate my majoring!!!)
