« Yes, it's worse than we thought. | Main | Lower Manhattan gets swallowed up by Sandy. »

In a fascinating recent article in the NY Times, David Ewing Duncan, author and contributor to Science Times, discusses the science of aging:

How many years might be added to a life? A few longevity enthusiasts suggest a possible increase of decades. Most others believe in more modest gains. And when will they come? Are we a decade away? Twenty years? Fifty years?

Even without a new high-tech "fix" for aging, the United Nations estimates that life expectancy over the next century will approach 100 years for women in the developed world and over 90 years for women in the developing world. (Men lag behind by three or four years.)

Whatever actually happens, this seems like a good time to ask a very basic question: How long do you want to live?

Great question, right? As it turns out, most of those surveyed aren't that into hanging around for that long:

Over the past three years I have posed this query to nearly 30,000 people at the start of talks and lectures on future trends in bioscience, taking an informal poll as a show of hands. To make it easier to tabulate responses I provided four possible answers: 80 years, currently the average life span in the West; 120 years, close to the maximum anyone has lived; 150 years, which would require a biotech breakthrough; and forever, which rejects the idea that life span has to have any limit at all.

I made it clear that participants should not assume that science will come up with dramatic new anti-aging technologies, though people were free to imagine that breakthroughs might occur -- or not.

The results: some 60 percent opted for a life span of 80 years. Another 30 percent chose 120 years, and almost 10 percent chose 150 years. Less than 1 percent embraced the idea that people might avoid death altogether.

Less than one percent wish to live forever! Now that's a surprising finding, eh?

How long do you want to live?

While you ponder that question, why not listen to a song of ours that has a similar question as it's title: "Doesn't It Feel Great to Be Alive?"
