In addition to the number of candles on a birthday cake, the study's subjects also pointed to physical or personality changes as evidence of aging. Some women determined their youth had fleeted at the first sight of gray hair, and others said acting like their mother was a sure sign they were over the hill. Gray or not, men felt past their prime when they could no longer perform in the bedroom.
A psychologist gave the Daily Mail his own relatively retro explanation: "At 30, women have matured, they're expected to think about getting married and starting a family. While the majority of men are much more career orientated — they don't feel old until they've reached retirement age." I'd counter it's not men's superior focus on their careers, but rather society's more laxed standards of male beauty that allow men to feel young past middle age. While salt-and-pepper actors remain sex symbols, the female ideal, seen on fashion runways for example, is often a 15-year-old girl.
Besides maybe the fact that '90s Nickelodeon shows are now vintage, what has made you feel old?
