Immortality means forever, in the first place. Beyond the end of the universe, then. I think long before that, as the sun shrank down to a hard little ball without light or heat and with extreme gravity, I would be getting very uncomfortable.

In the second place, immortality requires a zero birth rate. I kind of like new people turning up now and then. During my eternity of life, I would eventually know every single person very, very well. No surprises left.

Third, as people get older they seem to get less flexible. We'd all be living forever with our solidly fixed opinions and quirks. I can see everybody ending up alone.

Yea I dont think anyone when discussing biology means forever immortal, just not aging. Which Id gladly accept, and then terminate myself at some point, probably earning myself a very late Darwin award. As I got bored Id probably start some fairly extreme risk taking.

Well, yeah, literally. But what if you never aged, never died of old age or disease. You could live for 500 or 5,000,000 years if you wanted to...and suicide long before the sun went all red giant up in your grill.



True if everyone is immortal. What if only you were immortal? Or you and a loved one? Or you and a small community of 100 people? Then everyone else could keep on birthing and dying.




There's a great science fiction story about an immortal population that put themselves in suspended animation and came out of it periodically in a computer controlled schedule, so for millions of years they could experiencing a unique combinations of personal interactions. also, they had their minds temporarily wiped on each 'birth', so they could periodically have the experience of having new experiences, even if they later discovered them to be repeat experiences when they eventually regained their original memories.




There may be biological factors influencing this, and they may be addressed if we fix the aging problem.

Also, what better way to shake off the boredom of the centuries than deciding to completely and thoroughly reinventing yourself? I could see what you describe happening, and i could see the opposite, also. People going way out of their way to expose themselves to the opposite of what they previously believed and preferred.

There is physical immortality and spiritual immortality. I like the series "The Highlander" where they are physically immortal... if and only if they get killed before they live out their lives. If they don't get killed, the immortals can grow old like normal people. If they are killed, they remain looking the same as they did when they were killed.

Here is an interesting thought for that show. What if a two year old immortal or even an infant got killed when very young? They would have to spend immortality as a small child until someone cut off their head.

That would have made an interesting show. A woman who has a baby that stays a baby forever.

hm all that would ned to happen is certain genes manipulated scientsists now are very close on that

Life expectancy is environmental. The thing we're taught to fear, global warming, actually will improve life expectancy dramatically. Of course the globalists will continue to try and poison us to maintain status quo.
