You can of course be unlucky and you can obviously wreck your health. Hint, damage you do to your health after 40 doesn't go away.
They made a whole movie about it! https://www.imdb.com/title/tt0070723/
Something else I ponder, which helps, is that since life is not well-defined, then neither is death. We perceive a difference, but it is fuzzy. We're constantly dying, but also can never really die; as walking, talking sacks of chemicals there is a sense in which we were never really alive in the first place.
We sink back into the chaos that birthed us, not as finite isolated beings, but as waves that rise above the ocean for a moment before returning their water for the next wave.
"Why tiptoe through life, to arrive safely at death?"
--Christopher Brian Bridges
