I added a year because it was a nice round number of 3/4 of a century and a decade past the risk period, and I probably shouldn't have. I imagine the risk period could be a little off, but the say 65 because it is a nice round number.
I'm not playing the food police because he had a burger every week or three. I am playing the food police because he eats burgers and other fast food every other day and generally doesn't eat very many vegetables. That has been proven by him, those around him, and his doctor who tried to place him on a diet that is not as unhealthy as his diet is. It was at cause that his blood pressure is high for a man who doesn't drink, or smoke because of his eating habits.
I eat MUCH healthier than him but I smoke a pipe for 6 or 8 years,(and a pack of cigarettes for the 20 years before that) and I would say the same thing about myself if I were over 65 at cause of smoking instead of dietary habits. I am not telling him what to eat, I am simply pointing out the risks of his being 74 and having those eating habits for much of his life. Just like I would point out my risks if I were over 65 due to my smoking habits. Facts are facts, whether dietary or through smoking habits.
I believe there are several reasons they believe the unnamed source over his doctor. One, because they are biased against him. Two, because his doctor is at risk of being fired if he doesn't say the right things, as proven by his past firing habits. And three, because he works his will to manipulate the press around him, at almost every instance through his presidency, through lies and obfuscation.
