Will I be practicing martial arts at 90?

I came across this video featuring Len Kovar, and I thought that anyone could appreciate it. Mr. Kovar turned 90 and to celebrate, he decided to spar 10 rounds...quite impressive. This serves as an inspiration to all of those people who think that they are too old to start up martial arts. Quit making excuses. After all, in a safe and science-based program like Johnson's Tiger Rock in Cary, you can have a great deal of longevity in the sport of martial arts. What are you waiting for?
