Wow! Your research paper and podcast sounds great! We put our now 8-yr old son in Tai-kwon-do a little over a year ago. We wanted the physical and mental activity and the discipline. Our Grand Master runs a tight, old school ship. It is wonderful! If you saw my son at home or in school and then at martial arts, you wouldn’t think he was the same person. It is the best thing we’ve done for him so far. Unfortunately, the benefits don’t seem to carry over into life outside the dojo…or maybe they do, and he would be much worse… I will definitely take a look at what you’ve done.
