Feeling younger than your age may not be entirely in your head. Developing research claims that your biological age may indeed be younger (or older) than the age on your driver’s license. And there may be simple solutions to help you reverse your biological age (by a small amount) and improve your overall health and wellness.

“Simply put, biological age is the rate at which you’re aging physically, whereas your chronological age is simply the amount of birthdays you’ve celebrated,” says Dr. Kara Fitzgerald, a physician and clinic director at FxMed and author of Younger You. “There’s nothing you can do about your chronological age, it’s always going to increase by one every year.”
