Scientists haven’t figured out a really good way to measure the rate of aging yet. But there’s progress, as I wrote in the New York Times this week. The growing evidence that “epigenetic” changes are correlated with chronological aging, and possibly can be used to get a handle on the rate of biological aging, is one of the most promising recent developments on this front. It’s especially important stuff, in my view, because we need good biomarkers of aging in order to assess the human anti-aging effects, if any, of drugs like rapamycin, which appear to slow aging in mice.
