pdq, Clinton was a younger man, although he was not in good shape, it turns out because he did have a heart attack. But he didn't die.

McCain smoked two packs a day for 25 years. 6 different medications.
His health is relevant because he is applying for the highest office in the US.
he would be the oldest president ever to serve.

He is being stingy with his health records. He is trying to keep something under wraps by
not allowing this information to be made public.

McCain may have psychological issues as well. His flip-flopping on what he says during
his press conferences and not knowing basic things such as the borders of Afghanistan or Iraq or the difference between Shi'a and Sunni may be characteristic of his ability to make
sound judgments. Americans can't take that chance with a president.
