I have been listening to a lot of YouTube science while I paint the house.
I love this guy- Stefan Milo. He's delightfully curious.
Here's his video about Sinus Infections. Every kid on the planet should see this when they're 8 years old. And be taught proper hygiene methods. It would have changed the entire trajectory of my life.
(He also discusses the recurrent laryngeal nerve, which is one of my suspects for Tourette's symptoms.)
