I find it interesting that we practically crawled inside Reagan's colon with his doctors, but never heard any more about Obama's physicals than the doctor suggested he stop smoking.
I'm not so sure we ever know all that much about any president's or presidential candidate's health. Whatever we are told is never the whole story. Even President Reagan -- when we finally did learn he was diagnosed with dementia well after he left office, there were rumors he may have exhibited symptoms during his second term. And when he was shot, the public wasn't really told how serious his injuries were.
This ticks me off. I believe we should be informed as to whether our president or a candidate is healthy enough for the job. As a voter, I don't want to elect someone who might croak a week after he's elected, or be crazy enough to launch a nuclear strike on Canada.
