The astounding 93-year-old Leland McPhie could tell you, after picking up gold medals in the high jump, discus, and shot put at the USATF West Region Masters Championships in Occidental College in Los Angeles, CA. That's 200+ gold medals for this 1937 collegiate champion.
A fun article on Leland here at the San Diego Times. He sounds like quite a character! I can only hope to be this active when I hit my 90's.
