why do people who smoke and drink heavily sometimes outlive heathy people?

Question

So people who exercise, eat healthy and never touch drugs or excess of any kind and do all they can to stay fit only to die so soon into their lives?

But then you have people who drink, smoke and do drugs in massive amounts for ages but they last for a long time all things considered and sometimes way older then other average people

This isn’t the case for all of them but it happens enough to be noticed

So how and why does this happen?

Thanks for reading and have a nice day

Answer 1

The answer isn’t any one thing. You actually have to look into each case (of death) to see what happened.

In general, though, smoking has bad effects on the lungs, and drinking has bad effects on the liver, and we have more organs than just those two, AND more ways that they can be damaged than just those two. Obesity affects the heart and circulatory system (blood pressure), and then there are cancers (any organ, potentially), car accidents, and any number of diseases and medical conditions.
