Hehe, I came up with the exact same thoughts when
considering the stupidity of the concept of heaven.
As for Immortality, I'd want to live a hell of a lot
longer than 140 years. Everything you said is true but
it'll take more than 140 years to get bored due to
exhausting all your entertainment possibilities. Since
Immortality is much closer to solution than most
people think- I for one am looking forward to it.
(Immortality- are you up on advances in antiagothics
and nano research, ect.? Not going to turn you
immortal overnight but can extend your life till the
next advance is developed, till true Immortality is
developed. Of course, someone can still always take a
shotgun to your head :-))
