Not far behind you. An uncle had a major bypass heart operation in his 60s, after which he started daily 4-mile walks and he's still doing pretty well 15 years later. Inspired me to start daily walks earlier in life (usually about a mile) and a few sessions of exercycle and karate every week. The other ingredient which I have only been recently aware of (thanks in large part to reading "Why we sleep") is getting a full night's sleep. That's hard for me, because I am naturally a "night owl" and light sleeper with kids who need to get up early, but I am aware of the need and try to get 7 or 8 hours as best I can.
