I can provide many more: this "bug" is a field of science that many, many papers have addressed: I'm being downvoted because few people here are mature enough to do their own research and instead prefer a "cool, wacky, zeitgeist" take on it.

Trust me: about 100 years of biology has been done on this "bug". The OP piece is a joke.

You're still coming off as as really, really insulting. That doesn't help you get your point across.

Besides, you're missing the main point, which is "Wow human biology is a huge mess." Did you read the part about the same hormone being related to both blood pressure and pair-bonding?
