And I go, well, what do you mean disgusting? And I kept coming up with these lists of things that people all around the world found disgusting. And it was a motley collection of things. I couldn't figure out what connected that all together. But then a colleague asked me to explain the cause of a strange parasitic disease. And I looked it up in a book about communicable diseases.

And suddenly I realized all these things that people found disgusting were sitting in the index to this book. And I'm going, hang on, vomit, people find that disgusting. It makes you sick. Fallen hairs, people find that disgusting. Well, it's a cause of ringworm, food that's gone off that can cause typhoid, can cause diarrheal diseases.

So being an evolutionarily minded sort of person, I saw that this was basically an adaptation, something we have in our brain to make us behave in ways that avoid us getting sick.
