The Numero UNO predictor of how long you will live unless you are shot or run over by a car is........................how old your parents and grandparents were when they died. So if grandma and grandpa are in their 90’s and mom and pop are in their 70’s, I would break out the Hagen Dazs. Genes,sanitation,medical care and nutrition are what gets you to the golden years.
Don't forget a healthy dose of common sense in that list. Stupidity makes for a short life expectancy.
