It occurred to me the other day that fat – considered, in excess, a prima facie pathogen – has come to occupy the place of the medieval humours, and diet and exercise regimens, to make no mention of actual invasive surgery, are absolutely modern bloodletting. The parallels are actually kind of spooky: near-universal support from the medical establishment, temporary and perceptual gains in health, and, on the unlikely realization of its stated goal, mortality.
Physician, heal thyself.
