I was a red meat eating, cigarrette smoking , hard headed and hard working DA (that doesn't stand for district attourney) The thing I do to extend my life is Quit smoking anything. Stop eating red meat laced with fat and chemicals. Ride my bike 15 mi everyday attacking every hill I come to. Another big one is to let stress roll off your back. If you have a person that gives you problems in your daily life, it will cause stress. Nip that problem before it goes any further. Stress (the bad kind) will kill you as fast as any bad habit. the more in shape you are the more mental and physical stress you can tolerate. But don't tolerate it.
In essence Don't worry, be happy. Well, at least as much as you can.......
