Dave, John Pienta, Mark Moubarek, Matt Maves, and Levi Endelman are aware that the world is full of questions.  Nowhere is that more true than on the saddest place on the Internet, Yahoo! Answers. There folks ask the kinds of things that a primary care physician might have to answer.  What is the worst way to get rid of acne scars?  What could be the cause of blisters on one's lips after kissing one's dog?  How much milk should one use in one's bath?  There are no stupid questions. But first, since Matt has returned from a year in Des Moines doing clerkships there, we discuss what that's been like and the benefits of doing some clerkships outside a more academic setting.  We also discuss the psychiatric disorder pica and the kinds of things people swallow on purpose (or by accident).  Also we talk about drug maker Mylan's difficulties with, well, everyone after we collectively realized they're gouging patients who need epinephrine auto-injectors to keep themselves alive.  Meanwhile, a company is offering a supplement that its CEO, a pioneering MIT aging researcher, and it's Nobel-prize festooned board of scientific advisors say might just be a way to extend the human health span.
