New research from a team of Spanish scientists has found that body odor is not just a shockingly accurate biometric identifier, but could potentially change the way security checkpoints work. The findings from Universidad Politécnica de Madrid showed that body odor managed to correctly identify people with over 85 percent accuracy.

While humans have been using bloodhounds to sniff people out for centuries, such methods might not work in terms of airport security. But we reckon it's only a matter of time before they start installing special robots to verify your identity and sniff out any dangerous materials you might be carrying.  Sounds a little weird, but it's still a lot easier than getting frisked by a TSA agent!
