Re: mercury: When I took high school chemistry, we always played with balls of mercury on those long black lab tables, shooting them back and forth.
I mean every day, during lectures.
When I was a young nurse we used mercury thermometers. They were accurate. When one broke we cleaned it up. Then they were banned by the mercury police and replaced with electronic ones that aren't even close to accurate.
I'm not fond of big brother.
