The Census Bureau reports that average life expectancy in the U.S. rose above 78 years in 2006. Hooray. While the rate of increase is just a bit shy of 4 months per year, that's not nearly enough, It needs to increase by more than year per year to reach "actuarial escape velocity."
While I am unable to attend, reasonoids might want to check out the no doubt fascinating Understanding Aging conference at UCLA on June 27-29.
Live long and prosper.
