Maybe I'm missing something, but I didn't see anything difficult to believe. His weight is obviously in check, most 50 year old men are aren't fat are healthy, and the report says he quit smoking. Anyone can quit smoking. It doesn't make you a saint, just an ex-smoker.
Just the ex-smoking part. A lot of other indications pointed to the opposite. With this gang in the WH, truth is rarely to be found.
