Shot in the dark (coming from a MS in Biomedical Engineering): circadian control to stabilize the body’s metabolic activity to lessen the “wear and tear” of the body’s condition to intensely survive for but a cosmic microsecond. Once we can “hack” ourselves to de-couple the body away from its heliocentric regularity, we can “slow aging”.
After all, ex vivo cellular immortality exists. I think it’s the hormones that ruin everything.
That's interesting. I've always suspected that "curing" something as fundamental as aging would change some basic aspect of what makes us human. Per your comment about hormones, imagine that if you want immortality, you have to never have had testosterone or estrogen in your body. That person would have a vastly different human experience than everyone else. It sounds like it would make a pretty cool scifi story, as a matter of fact.
