Immortality for everyone would be a bad idea. This earth would get overcrowded very quickly, and resources would quickly be sucked up. We * need * to (eventually) die to make room for future generations.
Death doesn’t scare me at all. What scares me is the idea of *knowing * I’m about to die, and being terrified until it happens-- plummeting to earth for three minutes after a plane accident, for example. If my death is instant, I have no fear . . . I just don’t want to have a few minutes to think about it.
In my opinion, when you die, that’s it: the end of conciousness. I don’t think you’ll be aware of anything.
When I had my wisdom teeth taken out, I had full anaesthesia. One moment I was talking, and the next moment–nothing. I wasn’t even aware I was out until I woke. That’s how I see death. You’re just gone, no awareness, no conciousness-- nothing.
