I’ve been traveling around the globe for 55 years as I’m involved in a lot of businesses around the world and still play golf professionally. The bottom line is I have to have energy. It is one of the best gifts you can have. Energy is about maintaining gas in your tank. You need to refill. What do I do to build energy? I go to gym every day. At 72, I do 1000 sit ups a day. 200-300 of those with a 100 pound weight on my chest. If you want longevity, you have to be fit.
