One of my favorite PhD thesis chapters is now published in @pnas.org Using cohort mortality data from 12 countries, I find no evidence that the rate of aging has slowed down. Longevity gains seem more consistent with a later onset of aging. www.pnas.org/doi/10.1073/...

great paper by Silvio C. Patricio www.pnas.org/doi/10.1073/... His study shows no evidence that the individual rate of aging has changed. Instead, it remains stable, suggesting that gains in life expectancy are more consistent with a later onset of senescence than with a slowing of its tempo.
