On one of my birthdays I did 1,000 chin-ups and 1,000 push-ups. For my 70th birthday I towed 70 boats with 70 people in it, my feet and hands tied-my hands were in handcuffs, my feet were tied together-and I towed these boats a mile-and-a-half in Long Beach Harbor. For my 93rd birthday I'm going to tow my wife across the bathtub.
