I learned from my father's generation that regular check-ups were vital. My oldest two uncles died from heart issues in their early 60's. The next two and my father have made it to their 70's and show no signs of stopping. There isn't really any difference in lifestyles between the dead and alive ones, other than going to the doctor regularly, and taking whatever medicine they are prescribed. I guess one uncle quit smoking. So that's probably good for him.
