Interesting discussion here .
Even though I haven't really felt much doing tai chi except for being relaxed and cheerful after a training (wich I mainly attribute due to the fun/joking athmosphere at trainings)I felt something immediately when practicing qigong. In the beginning I got unconrollable joyful spasms (kinda like with laughing).
I think it's like my tai chi teacher told me: the first few thousand times you do your tai chi movement you're not really doing/learning tai chi. You're just learning the movement, and you're focussing on doing the movement right. Not until the moves are fully automatic will you really be able to do tai chi and learn.
Though, he also said people would still experience benefits from the start.
@ Chris D, I have no idea what you mean :/. And by the way, I dont have a job. I still study .
But regarding the computer use, I did realize it couldn't just be the my posture as can read a book mch longer with bad posture without getting the negative effects. And now that I though about it, I think it might also be a mental thing. So, I'm gonna try to be more mindfull behind the computer.
