 I am glad that Tom Whitwell has taken it upon himself to work out what all the facts are. And I'm always delighted to read his annual list of 52 things. Maybe we'll check in with him again at the end of this year to see what he's come up with. Thanks to Tom for the good conversation today. And thanks to you, as always, for listening. If you have learned some good things so far this year, send them along. I'd like to hear them. Our email is radio at Freakonomics.com.
