People constantly guess you’re older than you really are
Dean Drobot/Shutterstock When it comes to assessing a person’s “true” age, as opposed to their chronological age, our brains are pretty darn accurate, says Steven Austad, PhD, chair of the UAB Department of Biology. “Ask a dozen strangers to guess your age and the average value they come up with is a pretty good indicator of your body’s biological age,” he says.
Everyone is always telling you to hurry up
Are you constantly getting left behind when walking with friends your age? It turns out that a person’s normal walking speed is a pretty good indicator of how well you’re aging, Austad says. “Walking speed is an indicator of how leg muscles are working and says something about nerve conduction speed, two factors that go into aging,” he explains. Thankfully, this one has an easy fix: Take more walks and improve your fitness level.
You have more spots than a cheetah
Sun damage is perhaps the most important cause of an older-looking face, as too much sun causes lines, wrinkles, dull skin, and the dreaded brown age spots to develop, says Joshua D. Zuckerman, MD, a board-certified plastic surgeon at Zuckerman Plastic Surgery in NYC. If you feel like you have more of these than other people your age, especially if you never wear sunscreen, it’s a good sign your skin is aging faster than you are. Start wearing sunscreen immediately and talk to a dermatologist about other options. (P.S. Skipping sunscreen is one of the worst skin sins according to dermatologists.)
