As someone who really did come close to killing himself working out, I agree that I prefer to go all out. I learned my lesson in terms of lifting and going all out. Have precautions in place to prevent dying from dropping the weight on yourself. I'm changing how I work out, but I will continue to press. I'm 46. Seems like quite a few people get into running races as they get older, but running bores the hell out of me. I thought about getting back into golf and trying to be competitve, but that can be boring also. I actually have gone to a motorcycle dealer about how much support they could provide if I got into Supermoto, or road bike racing. They want to see the commitment first, but I like the idea so I may pursue that for the intensity buzz.
