A lot of people say, when it's your time, it's your time.

Agreed. I'm rather pragmatic about death, am not afraid of it, and figure after it happens I'll not care. Lol

a lot of stories where athletes, or really healthy people, suddenly have a heart attack, and died early.

This has happened quite recently with a couple of Australian sports personalities...It's a little confronting when these people fall off the perch and should serve as a reminder to others.

taking care of yourself minimizes the amount of risk you have

Indeed, and people should be focused on it...Physically and emotionally.

We all get lazy, (complacent is probably a better word), and take things for granted at times, I guess the key is to understand that complacency and arrest the backslide and get back on track.
