How Long Do You Want to Live?

This is good, from David Ewing Duncan, at the New York Times:

How long do you want to live?

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.

These percentages have held up as I’ve spoken to people from many walks of life in libraries and bookstores; teenagers in high schools; physicians in medical centers; and investors and entrepreneurs at business conferences. I’ve popped the question at meetings of futurists and techno-optimists and gotten perhaps a doubling of people who want to live to 150 — less than I would have thought for these groups.

Rarely, however, does anyone want to live forever, although abolishing disease and death from biological causes is a fervent hope for a small scattering of would-be immortals.

One hundred would be good for me, but we'll see. I think blogging shortens your life.
