So, what does it mean to "beat aging in a medical sense?" If it is just definitionally to not have any of the bad effects of aging, then sure. Of course I would want that. What are the names for the good things that are generally along for the ride with aging?
Going back to my earlier quip, if you could turn off aging for babies/toddlers, how would that be a good thing?
So the heart of my question is why do we view "defeating aging" as the same as "living longer?" Or is this something where the target age that people would want to be generally coalesces on a common number?
Wrinkling skin, graying hair, loss of muscle mass and bone density, loss of mental acuity, decline of libido, late-life diseases (eg: cancer, Alzheimer's, type-2 diabetes), and so on.
It's scientifically proven that our bodies spend enormous amounts of energy up into our 20s when we reach sexual maturity and then glide through on momentum through our 30s into our 40s when we are raising our children.
Once we're in our late 40s to early 50s we're done spawning new life and our bodies throw in the towel, starting the slow but inevitable deterioration culminating in death.
It's that whole physical process that we as a species want to overcome, we want to defy being just machines for spawning more machines. Life is fucking evil.
Growing wiser from more and more life experiences is also part of aging, but it's not what we refer to when we say "defeat aging".
