Cowboys can be people that herd cows, I suppose. They can also participate in rodeos. Rodeos are competitions with bull riding in which they try not to be bucked off a bull and can only hold on with one hand. Can also be a horse. There are timed competitions, but I know less about those. Usually roping and races.
I am more of a gunslinger. I was the law for a while, but I have a reputation for my ability to shoot with a gun. One of the fastest shots in the west.
Before all of that, I was a dentist. A doctor that works with teeth. When I was younger, most of it was cleaning and removal.
