An individual who takes care to eat healthy, be physically active within reason, gets to bed early and chooses not to partake in much that would work against their health is less likely to get sick. A hypochondriac or someone obsessed with outward appearances isn't going to live as useful a life as they could have had they spent more time living in accordance with nature. Live 80 years or live 90 years, there's truly no difference. It's more about whether you lived a good life for those 80 or 90 years or a bad one. We can now celebrate his life more fully as he lived to 80 and not just 75.
