Why do armpits smell? And how can we make them smell better? Chris Callewaert, also known as "Dr. Armpit," thinks he's solved this vapor caper.

When Chris Callewaert suddenly got body odor years after puberty had hit, he wondered how he could have suddenly become smelly. It timed out pretty well with a one night stand he had with a woman who had a similar smell to what he was noticing in his armpit.

He put two and two together, and came up with a hypothesis that the woman had transferred some new bacteria to his armpits. That's when he decided that he wanted to go from "Mr. Callewaert" to "Dr. Armpit" by studying the microbiome of armpits at Ghent University in Belgium.

Now a joint postdoctoral researcher at Ghent University and UC San Diego, Callewaert's testing out new theories for how to get rid of body odor for good.
