Why not? Doesn't smoke or drink.
Me either but my diabetes will probably get me in the end. The President's diet and exercise routines or lack there of and his age predispose him to problems like that. Add to that his age. It is a rare individual who gets to that age without some kind of ailment and the fact that it is known that physical problems of past president's have been kept from the public. He may be healthy and he may have been lectured to by the doctor about his weight, diet and lack of exercise. I don't know and you don't know. All we know is what the government and Donald Trump wants us to know. It is between him and his doctor. Personally, I don't care that much and don't know why this is so important to people. People can still perform their jobs well despite having diseases and certain illnesses and I can understand why we wouldn't want our enemies to think our president is sick or weak. Unfortunately sometimes these things are made obvious by ones behavior. IMO Donald Trump projects an image of mental unfitness to our enemies that I believe is a bigger problem than whether or not he has high blood pressure or cholesterol.
If it won't affect him doing his job I think those issues are between Trump and his doctor. I don't need to know what his blood sugar levels are or how much he weighs.
