overweight, bordering on obese. we know he takes medications including a statin drug to basically lower his cholesterol and propecia for hair loss. those are the basic things we know. what we really want to know is what has this last year done to him? we hear about his diet, cheeseburgers, drinking 12 diet cokes, fish-o-fillet sandwiches, chocolate shakes. all the stresses with being president as well. the thing you think about with a 71-year-old person first and foremost the doctors are going to focus on the heart, what are the risk factors for heart disease, then what are the risk factors for stroke, any particular cancers as well. i will tell you that a primary exam, a physical exam like this often does include questions like -- about anxiety, about depression, about stress. there may not be any testing accompanying those things but those are questions that are asked as well. >> yeah. i'm in my 40s. i get asked all those questions including about diet last time i went. sanjay gupta, thanks very much.
