Introducing A Thorough Examination

A Thorough Examination with Drs Chris and Xand

Available for over a year

It's the nutritional equivalent of smoking 100 cigarettes whilst going on a quit smoking course. Simple right? Well, it turns out to be far stranger and more emotional than either of them ever imagined...
