Ask Slashdot: What Happens If We Perfect Age Reversing?

ourlovecanlastforeve writes: With biologists getting closer and closer to reversing the aging process in human cells, the reality of greatly extended life draws closer. This brings up a very important conundrum: You can't tell people not to reproduce and you can't kill people to preserve resources and space. Even at our current growth rate there's not enough for everyone. Not enough food, not enough space, not enough medical care. If — no, when — age reversal becomes a reality, who gets to live? And if everyone gets to live, how will we provide for them?

      Just no.

      You are confusing Solar radiation with cosmic radiation... and they are largely very different things.

      The "solar wind" is largely photons and other, relatively low-energy charged particles from the sun. (Note the word "relatively".) Which is GOOD for us here on Earth. Because cosmic radiation has a much larger component of HIGH energy particles. The solar wind interacts with Earth's magnetic fields in such a way as to shield it from the cosmic high-energy particles.

      But it's the cosmic high-energy particles that penetrate far enough into the atmosphere to ionize particles of matter, which form nuclei around which clouds form. So... high sunspot activity generally means fewer clouds, which in turn means it gets hotter. When "solar storm" activity is low, more cosmic rays leak in, forming more clouds, cooling the weather.

      Unfortunately, it is these high-energy particles which require the most shielding. And in general, cells are more prone to damage than radiation-hardened silicon chips.

      They are "age related diseases" because age seems to be one of the main factors. If the body (and mind) stays young and healthy, a lot of those things are going to have a drastic decline. For cancer, treatment and survival rates are improving all the time.

      From a health care perspective, most of the cost comes from the elderly. If there aren't any more elderly, and they are instead working and contributing to society, universal health care actually becomes cheaper, medical technology improves faster (making those diseases even less of an issue), and so on.

      And people don't usually die of "old age" but of things related to it. When the body gets older, the immune system gets weaker, your bones and muscles decay, your brain gets messed up, and a lot of deaths are in reality just a mix of a bunch of factors that just result in the body kind of shutting down. None of that will happen anymore.

    We regulate whether you're allowed to drive a car, but we don't regulate whether you're allowed to have a kid. I submit that you can do a LOT more damage with the latter than the former.

    I think we really need a better social contract. We need to take better care of those who are alive, and do more to ensure that those who are born are more likely to be able to take care of themselves. If it takes a lot of work to be allowed to have a kid, you'll probably see parents invest a lot more in their kids. When somebody is born with autism or whatever, society can step in and lend a LOT more support. However, you won't just have masses of kids forced to take care of themselves because their parents were irresponsible.

    There is no reason that cradle-to-grave can't be financially viable, as long as you exercise control over the cradle part.

    Cry however you want over reproductive rights. I don't see how preventing somebody from trivially deciding to have kids is a greater injustice than much of what goes on as a result of humoring that urge.

    As far as who gets to reproduce goes, I don't think it has to be that difficult. At the very least, mandate education and some general weed-out steps so that those who aren't reasonably committed don't bother. Then you can screen for stuff like serious genetic disorders (by all means allow surrogacy and adoption instead). At that point you have to earn some kind of right to reproduce (that might be trivial or difficult depending on demand for reproduction vs slots available). The wealthy might be able to pay into a trust fund to simply buy the right (it costs society money to clean up after your messes, so you can prepay if you want). Otherwise, it might be a bit like applying for a scholarship - what have you done to give back to society, etc. Then for the sake of diversity you could have a lottery for x% of the slots where everybody has an equal chance of being able to reproduce regardless of merit.

Numerous potential flaws are most likely at the start of the system's existence, which is why infant mortality and miscarriage remain noticeable even with the most advanced medical support. And as bodies age, more and more smaller flaws accumulate to cause more and more profound system problems. These range from vascular problems, likely to cause strokes and aneurysms, to the wear and tear on joints causing motion problems, to accumulated heavy metal poisoning and debris in the lungs, to the ongoing risk of cancers.

    Until complete prevention or cures exist for all of those issues, it seems nonsensical to discuss the population issues of eternal life. Population _growth_ from people living even a decade longer is a much more real and noticeable issue in our economy and resources. So is the cost of medical care for those older people. We're already seeing problems with Medicare funding and elderly care being real economic and political problems in the USA.
