Weird Thought

So yesterday as I was washing my hands after going to the bathroom at the gym, I thought of something completely unrelated to working out. I'm sure someone out there has had this same question and same sort of thought process but I'm not sure that I know them. My question to myself was "Why do we wash our hands after going to the bathroom?" I'm not talking about when you take a number two. I'm talking about when you plop the 9 iron or maybe for those unfortunate men, plop out their inch worm and do work on the urinal. Assuming that most people take showers, what is so much dirtier down there than the things we touch in daily activities? People could be touching sick and old dirty people, the tires of their car, or someone's gum ball, but don't think twice about washing their hands immediately after.

I guess there is no point to this question. I was just thinking out loud on why everyone is so paranoid about washing their hands after they go to the bathroom. After all, don't some people in underdeveloped countries drink their urine to survive?

Sick.
