I feel life is so much more precious now that I understand there is no paradise, no resurrection or living forever. When someone dies young I really see it as a tragedy, where as before with the jw outlook, I just thought the resurrection has it all covered.
I can relate to what your saying though. But for me now, I think if we can live to an old age after watching our kids grow up and maybe even there kids, we have lived pretty well and couldn't ask for much more. Something will get us all one day, it's just a matter of what and when.
I really beleive that teaching kids they will never grow old and die, is extremely cruel and unhealthy. It is just as bad as teaching the child that they will be destroyed at Armaggeddon if they don't love Jehovah.
