Life extensionist believe they can extend life multifold. They may take drugs on the following list: Life Extending Drugs
Life regeneratists believe that in 200 or more years, mankind will be able to revive the dead. I do! So they have themselves frozen.
I wonder if that's what ancient the Indians and Egyptians thougth during mummyfication
Makes since, if you believe our species will just keep getting more intelligent.
I've read that our life expency has increased:
By fewer baby deaths. That would throw off the average. I've also read that better meds are the reason too, but unless it's antibiotics, I'm not seeing much coming from science (VIOX, steriods,...). The general concensious is that life prolonging drugs have been found and not released to the public. HGH (Human Growth Hormone) would be my pick. It actually reverses aging.
My guess is nature has designed us to live 70 years.
Changing your diet, taking aspirins, doing drugs and working out don't really change our life styles that much. Those different things aren't cumulitive. In other words, you quit smoking (adds 6 years to your life span), quit drinking (5 years). Together, they don't increase your lifespan 11 years. Dieting and exercise don't seem to our increase live span.
I'm only talking about this because I don't want to die, ever.
Twenty years from now, technology will be light-years ahead. But besides that, most of my good friends and best relatives are dead. I really don't want to join, ever.
