This claim that beards are good for you is unadulterated anecdotal nonsense.
In an investigation led by the BBC, beards were found to contain microbes that kill bacteria — in other words, a potential new kind of antibiotic.
First clue: the BBC is not a scientific institution. They’re a media company.
Second clue: they set up an imaginary conflict with a hypothesis by another media company: the New York Post.
By that point, the third paragraph, you can just dismiss the whole crapfest.
I kept going, but their whole methodology is pointless. They sent off swabs taken from men with beards to be dabbed on petri dishes, and some were found to have bacteriocidal properties. Whoop-de-doo. You can do that with dirt, too. Why are people surprised that there are complex and diverse interactions between organisms at the microbiological level?
