What exactly does it mean to shadow a doctor? You just follow him around all day? Is this really something that's highly recommended for medical school? If one of my parents is a doctor does this mean I've shadowed a doctor for my whole life? I see on many peoples mdapps "Shadowed Doctor - 2500 Hours"; is this serious? Do people really shadow doctors for so many hours? Please clarify what this all means, and I'm sorry if I'm coming off as ignorant..
