How do I know if I'm sitting in a chair right, in terms of posture?
(couldn't think of where else to post this)
You can either sit "right" and have a straight back, or sit comfortably.
that perfect 90 degree angle is just as bad for you as slouching forward
slight lean back is perfect, problem is finding a chair like that
If it's uncomfortable you're probably sitting correctly.
