Jim Van Horn, 65. What is the biggest challenge of staying healthy at your age? "Commitment to go every day. If I can spend three hours a day in the gym, I will." What is your biggest accomplishment? "That I'm still going!" What are your goals? "I recently broke my ankle and I'm about three weeks into recovery. I want to break the 5K record for my age." What is your motivation to stay healthy and active? "Probably just to continue to live as healthy, strongly and vibrantly as I have been for years." Do you have any heroes? "Afshin Gothbi. He was the coach at UCLA for women's soccer and I was his assistant coach. Now he coaches the Korean national team and is soon-to-be the head coach for the Iranian soccer team."
