I use this sentiment as a sort of a trick to help combat anxiety. There may be a billion universes in which I die this week, but it can’t be this one, because I am subjectively alive and experiencing this one. I can only experience the timeline in which I live. There may be other timelines, but I wouldn’t know about them, because I’m alive in this one. I don’t experience the timelines where I do/did die, by definition. I can only enjoy the one in which I don’t/didn’t.
