I don't totally believe in fate. I think some of our diseases are lifestyle diseases.
Heredity is a good starting point. If your family tree is littered with heart disease, diabetes, cancer, et al............there are things you can do to move the needle but you will be at a considerably higher risk than those that don't have those things in their family's health history. None of us are gonna outrun death. I'm gonna grab another beer and enjoy my time on this side of the dirt.
