In the world of hand sanitizer, body washes, and deodorant many of us tend to forget that we really are just gross (but very perfumed) animals.

Well, a study has come out to remind you humans do one very gross thing after shaking hands that's very similar to dogs smelling each other's butts. (And you probably don't even realize you're doing it!)

A new study published in eLife found that people inadvertantely sniff their hand after they shake someone's hand.

That's right. Researchers secretly filmed 271 people shake hands with someone and found that people touched their nose twice as much than they do normally in order to "smell" the hand of the person you just shook hands with.

The weirdness doesn't stop there.

It turns out the sniffing changes according to the gender of the person we shake hands with!

Men and women smell the hand they don't use for a handshake more if they just shook hands with someone of the same gender. But if they shake hands with someone of the opposite gender they sniff the hand they used.

Sniffing hands is what researchers call, "chemical signaling," a type of communication that goes on with chemicals that people are mostly unaware of. 

Of course, we all know that scent definitely plays a role in attraction; for example, it's been discovered women can tell whether a man is attracted to her through the smell of his sweat - seriously!

Gotta love weird science!
