Larger population sure, but there are far too few left with enough honer to duel like men. There would be a lot of people being shot in the back now days.
Honor or Common Sense? I remember my favorite dueling story. It involved a Senator named Benton (I forget which state) and a guy named Lucas, I think 817-1818 or thereabouts. Anyway, Lucas challenges Benton to a duel at the traditonal 10 paces. The Senator shoots Lucas in the throat, Lucas shoots the Senator in the leg. Both survive. Traditionally, that would be it, bygones are bygones. However, Lucas demands a rematch claiming Senator Benton had an unfair advantage as he was a superior marksman.

The Senator agrees. Next duel is at three paces. Result? The Senator emerges without a scratch, Lucas is dead. Moral of the story? Know when to quit.
