Science has since shown the ancient Greeks were right – liver failure and diabetes and many other diseases including infectious diseases give your breath a distinctive smell.

These signals in skin VOC signatures are probably how dogs distinguish between people by smell. We can also predict a person’s age with reasonable accuracy to within a few years from their skin VOC profile. Our recent research found by-products of this oxidative damage in skin VOC profiles.
