Welcome back to Martial arts. Thanks for sharing your story, I especially enjoy hearing from students that are over 40 and participating in martial arts classes. For me TKD has turned back the hands of time and is keeping me feeling young. I have made countless new friends, won some medals and trophies, learned some self defense, but most importantly I have had fun. My goal is to continue to participate until I am 80, and mayber later, depending how I feel. A former classmate of mine was 73 when he stopped, so 80 seems reachable to me... :-)
