Body Fat % used to calculate obesity

At my new workplace in Poole, Herbalife gave a free "Personal Body Analysis", a 1 minute test for body fat percentage (body fat %). At 168 pounds and 5'7.5" and 57 years I had BMI 25.9 and 29.7% body fat.

Tanita have an explanation and wall charts showing that I am classed as obese (just) based on body fat % basis. The wall chart was based Gallagher et al in 2000 according to Tanita.

Body Fat Ranges for standard adults

The wall chart was based Gallagher et al in 2000.
For males 40-59 years a healthy body fat % is 11-21%.

Tanita's Body Fat Monitors and Body Composition Monitors use Bioelectrical Impedance Analysis (BIA) to help calculate results.

Searching for Meaningful Markers of Aging - David Stipp - “epigenetic” changes are correlated with chronological aging

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.
