3. Lloyd Kahn first tried skateboarding at 65. He stood up on a board, fell immediately, and hurt his hand. From that experience, he concluded that he should wear full protective gear: knee pads, elbow pads, a helmet. Lloyd, who is now 79 years old, said: “I don’t do any special tricks. I don’t ride like the teenagers. I try not to go too fast, so that I could always jump off and land on my feet.”
