Why I'm so afraid that one of my family members dies by cancer or so? My father smokes a lot. What are the chances of die young if you don't smoke or drink lots of alkohol like my bro?
Depends on your habits but the chance is literally a flip of a coin.
You died or lived. It's random. Look at Zyzz. Healthy guy, still dies from some freak heart attack. I know people who are alive at 70 and have smoked daily for more than half a decade.
