Okay, so chemo signals are basically chemical signals

And we emit chemical signals all the time.

We like to think that we're beyond that.

But as I always argue, we haven't evolved our way out of being animals.

And by the way, if you want to pass some time and just have your mind blown, read upon chemical signals and chemo signals for humans, because there are all these experiments which show that

that we give off sense when we are happy, when we are sad, when we're scared.

And if you think about this with the rest of the animal kingdom, you're like, oh, that makes sense because they can't communicate as well.

So, you know, oh, the person next to me is scared.

Maybe there's like, I don't know, a wolf nearby or something, right?

It turns out we have a similar thing.

There are these experiments where they basically get people to put gauze under their armpits.

They're not allowed to wash or use deodorant or what have you.

And they get them to watch like happy films or sad films.

And then they take that gauze, they give it to a different group of participants.

And they're accurately naming the emotion.

It's wild stuff.

And so the argument has been that a handshake is a good way of passing along a chemical signal.

It's a good way of assessing somebody upon a first meet.

And actually using hidden cameras, they were able to show that people are more likely to put their hand to their face and sniff it after a handshake.

Yes.
