Didn't Teddy Roosevelt get shot, and then give an hour plus speech before seeking medical care?
I don't know how long the speech was, but he finished it.
It was in 1912, when he was the Progressive "Bull Moose" Party candidate.
Folded up notes in his pocket absorbed most of the energy from the bullet, so it didn't penetrate very far. He was bleeding.
Not nearly as manly as holding up a Bible he'd never read in front of a church he didn't visit, though.
He died less than 6-1/2 years later at age 60. He never really recovered from a 1913-14 trip up the Amazon to the "River of Doubt"--now known as Rio Roosevelt--in far SW Brazil. [EDIT: Actually, the trip was cross-country to the headwaters of the Rio Dubido (now Rio Roosevelt), then downstream, ultimately to the Amazon. He got a leg wound when he jumped into the water to keep two boats off some rocks, it got infected, and he became delirious. His temp got to 103 and he asked to be left behind so that he wouldn't slow the rest of the party down. He planned to commit suicide with an overdose of morphine. When he got semi-recovered back in the USA, he wrote a friend that the trip had taken 10 years off his life.]
And then he absorbed another terrible blow when his youngest son Quentin was shot down and killed in combat in July 1918.
He likely would have been the GOP nominee in 1920 had he lived longer. The party establishment had forgiven him for his apostasy of 1912.
