I wonder if it can affect stress. There is some evidence gut bacteria feed stress-inducing whatever back up to the brain via this nerve, and that stress promotes abdominal (inside it) belly fat deposition, as opposed to more distributed body fat deposition, which in turn releases chemicals which cause insulin resistance, which is the main cause of Type II diabetes.

People will still die even if everyone gets the treatment. They'll die from war, accidents, and diseases. They'll still have heart attacks and get cancer. I suspect even if you completely "cured" aging at the cellular level the average life span would only go up by a few decades.

Consider cancer. The human body has multiple overlapping systems to detect cells that have gone bad. It doesn't cure them, though. It kills them. One of the reasons cancer normally (not always, but normally) strikes in old age is likely the systems which detect and kill cancer cells have been shot full of holes by... the systems that detect and kill cancer cells. That's not going to stop. Your odds of being a cancer victim (albeit more youthful looking) in your sixties and seventies probably won't change very much.

There are other problems that youthful cells won't help with. The heavy drinkers and drug users are still going to drop dead by age 50 or so. Women will probably become infertile about the same age they do today. Morbidly obese people might live a few extra years, but probably not as long as thin people today (statistically).

Actually extending human lifespan appreciably is going to require far, far more than addressing cell aging. So fear not! You're still all gonna die.

The whole idea rests on some questionable pop history. Much of what people claim to be the product of the "space race" was developed far earlier for military or commercial uses. Velcro, for example, commonly cited as NASA breakthrough was actually patented in Switzerland in 1948. If we're going to pour resources into something, instead of doing a pointless vanity project like a moon landing let's do something useful this time. Nuclear fusion, for example, or diabetes research.

I am bothered by technical capabilities being copyrighted instead of patented, and thus never expiring. Apple's Macintosh "look and feel", anyone? Most of that isn't a particular style of horizontal line thru a window bar at the top, something that might be a legitimate copyrightable thing.

I understand what you are saying, but the public are not the rightful owners, either. After the patent or copyright expires, nobody is, and hence anyone is free to use it.

This is a philosophical difference, and I refuse to participate in some The Glory Of The People rhetoric. You don't get to own something simply by pure numbers.

It's worse than that, though. Grid maintenance costs are rolled into the per-kWh charges in most places (definitely in CA). The power company is buying power from its suppliers for five or six cents, and then selling it to consumers at a much higher rate (22 cents the last time I looked). That difference mostly goes to pay for the power company's overhead. So when you sell power back to the power company at retail rates your neighbors are subsidizing your use of the grid.
