lol I keep moving my legs a lot lolllll, anxiety is harmful to everyone's health, but in poker there is that adrenaline, I usually get very anxious but I try to keep the focus mainly on the final stretches that our decision making must be accurate!
Having practice breathing to calm myself down and cut that anxiety factor.
But this is a point that everyone has difficulty with and we have to train all the time, not just in poker but in life!
Poker anxiety disorder: It leads you to make mistakes ex: playing tournaments at the beginning, spelling straight lines etc...
Tip always play poker when you are calm and with only one purpose in mind (make the best decisions!!)
