They say time is the fire in which we burn: 'Old age begins at 27.'

Geritopia: the endless war between the Senior Citizens' Center and the rest of Randolph Township has gone national.

It has become increasingly clear to me that Sun City, the Villages, and thousands of other "voluntary ghettos" around the nation, are neither sustainable nor accountable. Rather, they are a fantasy, the product of a developer's profit-driven concept of "geritopia."

Sustainable communities aren't based on leisure. Living among a community of aging peers and golf courses may be comforting and a lot of fun, but a complex and functioning society demands cooperation between the generations.

No one can live in a bubble, regardless of how pleasant the initial experience may be. As Arizonans may remember, even Biosphere 2 eventually needed oxygen pumped in. Similarly, without new generations and reinvestment, and the constant renewal they bring, it is hard to imagine how these communities will survive, much less prosper over time.

And then there are the rest of us. After defeating 17 school-bond measures in 12 years, de-annexing from the local school system, and all the energy spent evicting "contraband children," Sun Citians can likely forget relying on the goodwill of their neighbors who often share a reciprocal bounty of distrust, anger and apathy. Shown in this light, Sun City's claim to fame - community service - rings rather hollow.

Life in the Villages is similarly premised: Seniors have taken control of their county's political machinery and have already begun closing parks for young families who live outside the gated community. As one Villager proudly told me without a trace of irony, "In the Villages we spend our tax dollars on ourselves."

A glowing WaPo profile of futurist Aubrey de Grey, who has personally assured me that I will never die.

Aubrey de Grey may be wrong but, evidence suggests, he's not nuts. This is a no small assertion. De Grey argues that some people alive today will live in a robust and youthful fashion for 1,000 years.

In 2005, an authoritative publication offered $20,000 to any molecular biologist who could demonstrate that de Grey's plan for treating aging as a disease -- and curing it -- was "so wrong that it was unworthy of learned debate."

...

In the end, they decided no scientist had succeeded in blowing de Grey out of the water.

But it gets more interesting as de Grey gets more and more Utopian:

"Of course the world will be completely different in all manner of ways," de Grey says of the next few decades. His speech is thick, fast and mellifluous, with a quality British accent.

"If we want to hit the high points, number one is, there will not be any frail elderly people. Which means we won't be spending all this unbelievable amount of money keeping all those frail elderly people alive for like one extra year the way we do at the moment. That money will be available to spend on important things like, well, obviously, providing the health care to keep us that way, but that won't be anything like so expensive. Secondly, just doing the things we can't afford now, giving people proper education and not just when they're kids, but also proper adult education and retraining and so on.

"Another thing that's going to have to change completely is retirement. For the moment, when you retire, you retire forever. We're sorry for old people because they're going downhill. There will be no real moral or sociological requirement to do that. Sure, there is going to be a need for Social Security as a safety net just as there is now. But retirement will be a periodic thing. You'll be a journalist for 40 years or whatever and then you'll be sick of it and you'll retire on your savings or on a state pension, depending on what the system is. So after 20 years, golf will have lost its novelty value, and you'll want to do something else with your life. You'll get more retraining and education, and go and be a rock star for 40 years, and then retire again and so on."
