I might add "campaigning" as an answer to the assassination attempt. He had yet to actually begin speaking when he was shot (and the speech in his pocket helped stop the bullet!)
And he went on to give the speech anyway in spite of bleeding through his shirt. He quipped that it would take more than getting shot to stop a bull moose.
There's a great book about him that I just read called "The River of Doubt." It details his trip down an uncharted river in the Amazon to which the penultimate question refers.
But I knew Juan Valdez wasn't V.P.
