It activates the same chemicals in your brain as cocaine! 
Well, yeah, there are only ~~three~~^[@Neuromancer49@midwest.social corrected me] a few neurotransmitters. That's not saying much.

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.
I am a solo act, doing some pretty avant garde stuff. Tends towards screaming based chants at the news and spoken word anti-LLM multi-hour long screeds.
