How one molecule is changing the way we view human aging and health.

Ever since the first human saw their reflection in water, we've sought to reverse—or at least hide—the effects of aging. Our efforts over the centuries to thwart aging have led us to some rather scary methods. The ancient Egyptians basically invented cosmetics, developing hair growth serums for men and night creams for women. Some even turned to leeches and crocodile dung as elaborate topical treatments designed to make them appear healthier and younger.

Diets, working out, and staying hydrated mean nothing without this.

Do mixed drinks really get you buzzed faster?

1. Don't drink on an empty stomach

The biggest factor in how quickly we get our buzz has to do with the stomach. Eating before, during, or after your favorite drink will slow down how quickly alcohol is absorbed into the bloodstream.

Alcohol has to pass through our stomach first and then our intestines before it can give us a buzz. Digesting food slows down this process.
