Strange in the same way it's strange that people might say that playing Russian roulette increases risk of death by an easily-calculable amount.

Could this be meant as "risk of death at certain age"?

Obviously that's what they mean. It's just funny :)

What if you eat a lot of vegetables though

Would that make you immortal? If not, still 100%.

I am guessing they mean premature death.

So far.
