Smile on a Baseball Card and Live Longer (and maybe also Prosper More)

One often hears comments that people who smile more live longer, which has to do with the positive emotions. But how to test this? Well, how about with baseball cards. Now that's pretty damn cool!

And in other news, I have a book deal. And I'm going to try to be concise when I write it. Stay tuned. (Or ask me, but I have to actually write the book first...)
