True.

You're not going to live forever, but you can put the odds in your favor as to how, or how not, you are going to die.

There's no guarantee that you won't/can't get tongue cancer as a non-smoker or chewer. The odds state you will win the lottery first, though.

The odds go up if you chew, smoke, drink, don't exercise, partake in questionable lifestyles, etc.
