A semi-serious post:
All week long, the world wrings its hand and thinks “if John McCain wins, Sarah Palin will be one heart beat away from the Presidency!!! OMG!”
A review of Wikipedia’s page on Presidents Who Died In Office, indicates that Presidents generally don’t die by first losing their heart beat, ie ‘heart attack’, but by other, more preventable methods!
Four were assassinated (Lincoln, Garfield, McKinley, Kennedy), one died from pneumonia (Harrison), and another from gastroentitis (Taylor). Franklin Delano Roosevelt died from a cerebral hemorrhage.
Warren G. Harding was the only one, it seems, who died in office of a heart attack in 1923. Four presidents have been assassinated while in office, so that is a concern. But nobody goes around saying “If John McCain wins, Sarah Palin will be one bullet away or one uncooked steak away from the Presidency!! OMG!” because that would be tacky.

So, the chances any president is going to die while in office is slim to none. Joe Biden or Sarah Palin will just have to sit back, attend funerals and stay awake during the President’s State of the Union speeches.
And remember, this person is TWO heart attacks away from the presidency! OMG!:
