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.

I always assumed volume, def not mass, but what is it actually?
we don’t know becuase they never say! It’s usually words from a scientist, then someone writes a press release, then someone writes a pop-sci article on the topic.
knowing what I do about astronomy I’d guess it’s usually mass since that’s a fundamental descriptive quality of stars which determines the rest of their qualities. but we can’t directly measure mass we measure brightness, the spectra, and estimate the distance. these are used together to estimate the mass.
