who's the oldest person you've seem ? Ark Wong passed at 87, he was active till close to the end. YC Wong is getting up their, last time I saw him he was still teaching. Buck Sam Kong I think is still teaching, Wally Jay I'm not sure, I met them both in 2006.

I feel as though KF has much more to offer as we age, than, other M/A styles. "When I was young and in my prime I fought all the time - now that I am old and gray I exercise for health everyday" quote from GM Bin-Go-Lau.
