If you have not done so already, head on over to Doc Rob's blog and have a listen to the first (and hopefully not last) podcast, cleverly called Doctors Unmedicated.
There you will meet Doctor Rob, who blogs under Musings Of A Distractible Mind, and Doctor Clay, formerly known as Dr. Clark Bartram of Unintelligent Design. (Brownie points to the first person who can identify Dr. Clay's 2 other blogs)
I have long loved the interaction between the 2 of them and it really shows in their podcast. A lot of fun and a great discussion on the current decision of the FDA to pull cold meds used for children.
