[Fallout New Vegas] Why is a mailman so damn talented in Diplomacy and using a gun?

He/She has brain damage too.

The protagonist is not a *mailperson*, they are a *courier*. Their job is to take an object of extreme value, and move it from one end of the earth to another.

Couriers are essentially paid travelers in the most dangerous and hostile environment the world has ever seen. They have to step across warzones to deliver their goods. Not to mention the various bandits and 'interested parties' that follow people of such consequence.
