Can you smell a person’s age? Yes.

Your grandparents smell a lot different than you or your kids. 

Dr. George Preti, who investigates the nature and origins of human odors, explains the phenomenon of “old person smell.” It’s not an unpleasant smell, it’s actually less offensive than that of a young adult. That’s because the glands that produce body odor slow down as we age. In old age, before grooming becomes a problem, our scent becomes more subtle. Older folks also tend to stick to the same diet and routine which makes their smell easier to identify to the younger folks who hug them.
