On today's show, we've got a double expert special! Kristen and Jamie interview BMX legend and host of MTV's The Challenge TJ Lavin – and they dive deep into his past to see what paved the way to his biking and TV hosting success. Also, a special shoutout to TJ for use of his song "Remember the Time," available on iTunes!

Plus, they get into the stuff they've learned this week in their own fields. Kristen gives the lowdown on what foods can help boost your immune system, and Jamie stresses the importance of being a great writer.
