It's hard to pick between Theodore Roosevelt and Andrew Jackson. Both men lived in eras where modern medicine had just as good a chance at killing you as curing you, survived being shot (not merely shot at), and were both known for participation in wars. Roosevelt overcame his sickly youth to be, among other things, a cowboy, a police commissioner, Assistant Secretary of the Navy, and President. Jackson was shot more times than is healthy even in the modern day and age, survived being orphaned by the British, the whole of the War of 1812, and had to be stopped from visiting brutal blunt force trauma on a man who sought to assassinate him. I think pure precedent might give this one to Jackson, who simply had less technology to supplement his badass nature.
