I think luck of the genes has a lot to do with it. I still eat bacon and eggs nearly every day, coffee four to six mugs a day, red meat all the time, and my cholesterol numbers are tip-top good--without much in the way of exercise, although I was athletic in my younger days. For years I smoked three packs a day, until my son made me quit. I am on blood pressure meds, but under good control. Not bragging, just a data point from the field.
