Be careful out there

As a "nice" birthday surprise I ended up going into the dermatologist to have her look at a small patch of scaly skin on my forehead that had been there for a few months. It was nothing serious, but could become so if ignored, and was treated with a witch's brew of liquid nitrogen to "burn" it off.

For all those fair skinned Sherlock's living in sunny climes, lather on that factor 30!
