2459 Sweatphone

We've heard before that it's highly likely human sweat contains pheromones, those personal chemicals that convey varying degrees of sexiness.  It certainly makes sense, most animals, from bears to bees, exude some sort of scent that sucks in the opposite sex. Why not humans?  We gotta procreate too.  Survival of the species and all that.

Great pick-up line in an off campus bar, "Want to study Darwin?"

Scientists now say that human sweat does even more.  It can communicate whether you are happy or sad.  Researchers gathered a group of men, and carefully vetted them to make sure they didn't have any psychological disorders, weren't smokers, hadn't used alcohol nor engaged in sexual activity recently, consumed smelly food, or had a serious workout. 

You know, ordinary people.

They had the men wash their armpits and wedge an absorbent pad in them.  Then the men watched movies, some happy, some scary, some sad. 

The researchers recruited 36 women, also with the aforementioned prohibitions of behavior, to smell those sweaty pads.

Why the men did the emoting and the women did the sweat smelling wasn't discussed in the research paper.  Either because women are better smellers and men are more smelly, or because women always get the sucky jobs in the male-dominated scientific and tech world, that's the way it went.

In any event, researchers concluded that happy films watched by the men were detectable as happy pads when the women smelled them.  One woman actually said she smelled fried green tomatoes.  Fear and negative emotion were also detectable. 

My conclusions.  Dad was right.  Dogs really can smell fear on you.  And two, how can we harness this in a smartphone?  Sweat communication!  Forget texting.  We can have scented sweat emojis. 


America, ya gotta love it.
