How this works is that each time you die, your consciousness finds a version of you in a parallel universe that would die the same way but magically survives. And then it jumps to that body. There are infinite versions of you in infinite other universes so there's practically no way to end yourself. You will always jump to a new body... The con is that the new universe is somewhat different to the one you left behind, where your relatives and friends mourn your dead body...
Has any of you experienced something like this? An event where you almost died.... but didn't.. And since then you sometimes think "how the fuck did I survive back then?"... Well, this is the explanation
