There is not a lot of physical danger in the life of a dermatologist. A tanorexic could attack you if you mention that they should limit their visits to the tanning bed. In fact, a study conducted by UT Southwestern showed that the brain activity in someone tanning in a UV ray tanning bed is similar to that of someone who is addicted drugs or alcohol. Tanning beds cause rewarding effects in the brain, so people continue to use them. Getting someone to stop cold turkey might induce a violent or depressed reaction.
