Well your analogy falls apart, because we could just as well use horse drawn wagons as cars. 120 years does not an eternity make.
No one wants to die but when I die, and it is sure for us both, then what? We are all in the same boat. I think you also will face certain death from aging no matter what your faith. Right how I hope for life above 110 years and I have a very small chance of reaching it. But since life will be relatively short are you going to live in a bunker. I will take my chances and enjoy, knowing something is going to get me. How about you?
