It activates the same chemicals in your brain as cocaine! 
Well, yeah, there are only three[1] a few neurotransmitters. That’s not saying much.
You know what else activates those chemicals? Practically everything. When scientists breed “knockout” mice without dopamine, the mice just stand there until they die of thirst, because there is no reward for… living.
It contains more germs than a toilet seat! 
Germs like moist surfaces. We don’t want germs on our toilets, which is why we make them out of porcelain, which is hard, dry, non-porous, and easy to clean.
If it had more germs than your colon, then I would be concerned.

They did the toilet seat one on mythbusters. Iirc a kitchen sink had far more bacteria than a toilet seat, but the sink bacteria was mostly harmless while the toilet had some harmful bacteria.
