Life (aging) is a direct cause of cancer. And we can't change that unless we have some sort of nanobots constantly repairing DNA damage in every single cell of our body.
You realize the human body has a process thst cleans out damaged and misbehaving cells. Autophagy. This process is kicked off during periods of not eating.
We both expose ourselves to too Many toxins, eat too often, and don't get the right balance of nutrients over the long term.
If you can positively impact these things, then you can lengthen health span and lifespan.
Yes and no. While some cells may be impossible to rejuvenate otherwise, there are few reasons why we cannot just exchange many organs for dish grown ones, i.e artificially grown kidneys. For others like blood stem cells, we many extinguish the existing ones and add replace them by fresh ones that lack any pathogenic somatic mutations every so often. Even parts of the brain may be replaced one by one, though I assume such a technology is quite far away (compared to the other two that may be possible in the next 2-3 decades).
How's that related to this story? One outcome might have multiple factors affecting its probability of ocurrence. Just because you can't change life doesn't mean you can't stop alcohol. Life isn't 1 and 0 dude.
I can imagine aging being a technically solvable problem and maybe some of us will live to see it.
But if people didn't age, then there would still be a base rate of mortality from illness and accidents, and so for any arbitrary probability (99.9%, etc) there would be a maximum age that one could reasonably expect to live to.
For instance, if the only thing people ever died of was car accidents, at a rate of 20 per 100,000 people per year, then it would still be very unlikely for anyone to live more than 20,000 years. That's a long time, but it's not millions or billions of years, much less eternity.
Furthermore, if nothing but accidents killed people we might become extremely conservative and do practically nothing for thousands of years. Do I want to use the stairs and risk 99% of my potential lifespan?
So maybe one could say that biology and even physics don't ensure death, probability does.
