I volunteered on a farming community in Israel for two years when I was a teenager. One of the jobs involved clearing out a massive warehouse full of chickens ready for the abattoir. The smell of 40,000 chickens in 45C is awful.

My wife's brother has a little house on a small island in the Baltic Sea, and we go there at Christmas. The 30-minute crossing from the mainland to this island is the most terrifying cruise you'll ever take. They give you a barf bag when you walk on board.

We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.
