First off: doomsday argument. If you’re going to live that long, you’re not going to be in this part.
Second: if you live forever, it gives weird paradoxes involving probability. If you where to look at your watch at a random time, it seems like there’s a 50:50 chance that the second hand is on an even number. It’s trivial to move around events so that that only happens a quarter of the time. This would mean that the probability of things is influenced by their order. I find assigning zero probability to something less counter-intuitive.
For your expected lifespan value to diverge to +infinity, it is necessary to place only
.000000000000000000000000000000000000000000000000000000000001
probability on your chance of living forever, and I don’t think you can realistically defend assigning a probability lower than that.
