You can control your luck a bit though. Granted you could be in perfect health but roll a 1 five times in a row and get a heart attack when you are 40. Or you could be crushing junk food and alcohol but you just keep rolling 6s and make it to 80.

If you look at the sequence of events that happen to trigger a heart attack, it becomes really clear how big a role luck is, but still you can mitigate each step. Studying this stuff also makes your body seem like a walking time bomb.
