Death Life

AI Thread Summary

Natural death is primarily caused by the accumulation of cellular damage and mutations over time, which hinder the body's ability to function. While cells continue to divide, they can accumulate harmful mutations, leading to aging and eventual death. The Hayflick limit suggests that there is a cap on how many times cells can divide, which is thought to be a protective mechanism against cancer. The discussion also touches on myths regarding extreme lifespans and the feasibility of reviving the dead, concluding that once cellular functions cease, revival is impossible due to irreversible damage. Overall, while some cellular repair mechanisms exist, they cannot fully counteract the effects of aging and cellular deterioration.

Wait a sec, is there any research going on where they are trying to put freezing liquid in our body and see what happens?(they would need some suicidal volunteer for that though). I believe that the people who want to suicide should contribute to such experiments.(not if they can be stopped but sometimes, it is too much)

We don't need to try to freeze whole bodies to know that cells burst when frozen. It's hard enough cryopreserving single cells and small pieces of tissue without this sort of damage occurring, and doing it requires infiltrating the tissue with substances that have "antifreeze" properties, like glycerol.

But, since we've answered your question multiple times over, and the remainder of discussion has diverged off into philosophy, I'm going to close this thread here.
