From a discussion on Wikipedia, describing the implications of the “quantum suicide” thought experiment: that a physicist whose consciousness does not end when it is probable for it to do so would end disabled or disfigured in the majority of universes in which he survives:

“Here’s another possibility: in the majority of universes where the physicist survives, there simply is no explosion. If the explosion does occur, it is highly probable that the physicist’s body would be damaged even if he miraculously survives. This would probably shorten the physicist’s lifespan, thus pruning the number of potential universes in which he endures. However, if the weapon does not detonate at all, the physicist would have an excellent chance of survival in both the short and long terms.

I suppose that this question essentially asks whether the strategy followed by the universe is greedy. I confess that I don’t understand enough of quantum mechanics to judge whether a non-greedy strategy makes sense. It’s appealing from an algorithmic point of view, however.”
