I recently read an article by a doctor who had a simple recipe for a longer lifespan. You didn't need to go on a stringent, restrictive diet, or spend big bucks for a healthclub membership, or bust your butt with a strenuous exercise regimen. All you had to do was follow these three simple rules, and statistically, you would increase your longevity:
Rule 1: Don't smoke.
Rule 2: Don't ride on motorcycles.
Rule 3: Don't fly in private planes.
Makes good sense to me.
