Scientists and educators age fastest. Athletes age slowest. A facial aging clock trained on occupation-linked photos found that the gap between your biological face-age and your real age predicts all-cause mortality. The wider that gap, the higher your risk. Women aged slower than men in every single occupation measured. No exceptions. The ranking, from youngest-looking to oldest-looking relative to chronological age: Athletes > service workers > sales > clerical > managers > professionals > scientists and educators. The people who study aging for a living look the oldest. I wish I could say I'm surprised. Your face is a record of cumulative stress, UV, sleep loss, and metabolic wear. Your job title determines how much of each you get.
