Old people don't smell quite as bad as we thought. At least, that's the conclusion of a new large-scale study in which chemosensory experts found that "the underarm odor of 75-to-95-year-olds was judged to be less intense and far more pleasant than the scent of either young or middle-aged adults."
According to study co-author Johan Lundstrom, an assistant professor at the Monell Chemical Senses Center and at Sweden's Karolinska Institute:
This study shows you can't fake it. If you walk around a corner, you don't have to look at someone to know they're older; you can just sniff them out.
