I asked: Are you more healthy than a good dancer or gymnnast ? But. We shouldn't make any of this about you, or me for that matter. What about if we compare the average condition of a tai chi student at your school or a typical traditional martial school, are they as in shape as an average person at a dance class, or yoga, or something similar? Bet there's little in it or on average the tai chi people are in the worst shape. Nothing I have seen would indicate to me that these "health benefits" you keep mentioning are just a convenient story to tell, a semi delusional kind of story at that.
