The author of more than 50 non-fiction books and a leading physician, whose lifetime hobby has been the study of American Presidents, have teamed up to document an astonishing subject. This is the extraordinary story of those American Presidents who have suffered illnesses or injuries so critical they have threatened not only the man in the White House but the entire nation. Here you will find a startling behind-the-scenes story of the nation's chief executives who have been stricken-some to the point of being unable to remain on the job.
