This November, at 73 years old, Dr. David Minkoff will head to Hawaii to compete in the Ironman—the famed triathlon known for testing physical endurance and mental toughness. It won’t be Minkoff’s first. It will be his 44th. In today’s episode, Dr. Minkoff will tell you why he pushes himself to finish a race men a third of his age don’t dare to enter, and how you can benefit both mentally and physically from challenging yourself no matter how old you are. His story will inspire you to get up, get out, and push yourself past your perceived limits.
