MY SOCIAL SECURITY COLUMN YESTERDAY led a couple of readers to recommend Ray Kurzweil & Terry Grossman’s book, Fantastic Voyage: Live Long Enough to Live Forever. Summed up, Kurzweil suggests that if you do things we know will help you live longer now — chiefly diet and exercise stuff, though I think he gets a bit carried away on supplementation, etc. — you have a chance of lasting long enough to benefit from more significant life-extension technologies in the future.

True enough, at least within limits. It’s hard to see how this could be put to work on a society-wide basis, though. And I’d be against efforts to try, as the health-Nazis are already out of control.
