Right, my point is that SENS research, which is a fairly new field, doesn’t have to be dramatically more successful than cancer research to produce tangible returns in human life expectancy, and the deceleration in increase of life expectancy is most likely due to a negative health trend which is likely not to endure over the entire interval.
Which is already built into the quoted longevity increases. (See also the Gompertz curve.)
