Two more things I can't understand:
1. Why do thyroid patients almost invariably wear turtle necks when visiting the Endocrinologist?
2. For the diabetic foot exam, why do some patients remove their shoes but then ask if they should remove their socks? Even better why do some patients only remove one shoe and sock and then ask if they should remove the other? I often ask in return: "Would you go to the eye doctor expecting only your left eye to be examined?"
