Quickly popping back to the non-physical immortality...I'd be happier if there was some concrete proof I personally could witness.
Kirlian photography, OOBEs (never had one), and other neat stuff is all supposed to be around us...but I personally have never experienced anything to suggest my awareness will survive death, and I've been very very close to dying at least once already

Isn't the fear of dying one of the main reasons people have such an interest in the concept of Immortality? If I was offered the chance to have my body returned to its prime and no longer age (still vulnerable to everything else) I'd snap it up. I'd still die eventually from either bad luck or illness or something, but who wouldn't say yes to that

Of course in the world we live, such a thing couldn't be available for everyone, we're already swimming in human bio-mass...so it would likely be priced for that top 0.01% that already have all the good stuff. Which excludes me, sadly.
What we need to go with Immortality is a gateway into the multitudes of dimensions that theoretically exist. Bye-bye population problems. Hello conquest of everything everywhere.
