If you seek advice from a very old person about how to become very old, the only person who can provide you an answer is a person who is not dead. The people who made the poor health choices you should avoid are now resting in the earth and can’t tell you about those bad choices anymore. That’s why it’s difficult not to furrow your brow and wonder why you keep paying for a gym membership when Willard Scott showcases the birthday of a 110-year-old woman who claims the source of her longevity is a daily regimen of cigarillos, cheese sticks, and Wild Turkey cut with maple syrup and Robitussin. You miss that people like her represent a very small number of the living. They are on the thin end of a bell curve. There is a much larger pool of people who basically drank bacon grease for breakfast and didn’t live long enough to appear on television. Most people can’t chug bourbon and gravy for a lifetime and expect to become an octogenarian, but the unusually lucky handful who can tend to stand out precisely because they are alive and talking.
