Saturday was the anniversary of Wilt Chamberlain's 100-point effort for the Philadelphia Warriors in an NBA game against the New York Knicks in Hershey, Pa.

It happened back in 1962, but Chamberlain, now 53, insists that he is still in game shape."I run. I swim. I do water aerobics. I run 5-10 miles a day. I do bicyling. I play tennis. I play volleyball. I do everything but play basketball," Chamberlain said in interview during a Knicks telecast on Madison Square Garden Network.
