Okay, let me blow your mind.
Imagine a multiverse that infinitely branches out. This multiverse is infinite and contains every possible thing that could ever happen.
So imagine your own life. You start traveling down a branch of the multiverse, and you come to a fork in the rode. You can either die, or survive.
In an infinite multiverse, there would be one "branch" that you live. And one "branch" where you die. Would your "consciousness" perceive itself to be living in the branch of the multiverse you survive, since the branch where you die does not exist and therefore cannot be experienced?
And to further this postulation, could it be said that it's possible that in an infinite universe with infinite branches, there is a branch where YOU, in THIS LIFE, are immortal? A branch where you decide to get Cyrogenically frozen? And then in the future, they figure out how to revive cyrogenically frozen people? And in this highly advanced future, the human species has figured out how to become immortal?
