I have an appointment with a vascular surgeon next week. I received a medical history questionaire, with all the usual questions. As I work my way thru the questions, I came upon 3 questions that don't have anything to do with my health history. 1 - Do you use seat belts? 2 - Do you have smoke alarms? 3 - Do you use sunscreen? I can see where #3 has something to do with my health history, as I have had skin cancer in the past. I don't understand what questions #1 and #2, have to do with my past health history.
