How long you live is determined partly by genetics. Some people take a licking and keep on ticking. Some don't. Docs have these formulas by which they can roughly predict how long you live. You can add years by not smoking or heavy drinking, exercise, and a good diet. You may not live to see 100 like george Burns did; but you'll be healthier. Btw, I believe the cigar was just part of the act for years.
