The origin of the absurd idea of immortal life is easy to discover; it is kept alive by hope and fear, by childish faith, and by cowardice.
I mean, first of all, let me say whichever superhero first came up with the idea of wearing a cape, he wasn't really onto anything good. The number of times I'm treading on that damn thing or I throw a punch and it ends up covering my whole head. It's really not practical.
