Physical Health Not Guaranteed

I've taken a different approach to life than my entourage. I don't smoke/drink, I workout regularly, I read, I eat well... I know that, while life doesn't offer any guarantees, these habits decreases the chances of something going wrong with my body.

Doesn't it make sense that if you take care of your body it's more likely to function better? Common sense, however, isn't common to all. I know people that smoke because it helps them maintain a "healthy" weight. How does that work?

In the end, we're not going to make it out alive. It's not about living forever but having a good functioning body for as long as possible. All we can do is find ways to decrease the chances of having problems as there are no guarantees in life.
