It certainly didn't kill my Granny and all of her ex-classmates who ran it around their palms.

My grandfather had a substantial quantity of the stuff when he was at work. This is probably going back to the 1960s back in the days either when he worked at the scrapyard, or when he was on the drain gang in the steelworks adjacent to my house. (Or maybe he was working on the bins at the time?) Anyhow there were some of those mercury coupling things or whatever they are (quite big things with mercury contained in glass cylinders) they'd been thrown out and when they were moving them they accidentally got broke. My grandfather gathered some up on a brick that was lying around (in the sunk in bit of the brick) and he kept it in the office. (Often as the doorstop) until it got knocked over one day and went down a drain.
Then there was my father who was fooling around in the science classroom at school (this was also the 1960s) when he knocked a big jarful of the stuff over and it went all over the floor. Well the teacher came in played hell, gave my father a ruler and told him to get the whole lot picked up. So he did.
It didn't do either of them much harm, nor the teacher who was still at the school when i turned up there 30 years later. Plus most of my aunts, uncles and my mother all handled the stuff at school and they used to throw it around. The Chemistry teacher also used to demonstrate the properties of mercury by pouring it out of the bottle and into a beaker and then sticking two rods into it to show how badly it conducted electricity (so we were all inhaling mercury vapour during that half hour or two it was sat on the desk in an open container). Not to mention the test tubes of the stuff they used to pass round that we shook about and threw around.
The physics teacher at school also had handled mercury at school infact his class decided to play a prank on their teacher and they poured a substantial amount into their teacher's coffee, the teacher soon disappeared to the toilet for the rest of the day, as mercury swallowed is a very good laxative. The guy survived unscathed.
Then there was my former geology teacher at college, she was teaching us in the same room she was taught in and she even showed us the filled in hole in the floor where she'd dropped a large mercury thermometer. It had picked up speed with the weight to such and extent it had gone through the florrboards on the first floor and into the groundfloor classroom below before shattering and spraying mercury everywhere.
Didn't do me much harm either when i dropped that mercury thermometer about 6 years ago... that was another ruler scooping up job. Thank god it wasn't on the carpet otherwise it would have had to come up.
Plus anyway i've been exposed to more mercury having fillings put in, removed and re-put in. I could taste the mercury for days after that last one went in. Generally as a poison i think it's a little overrated.
As a cumulative poison it's not too bad in small doses (as long as they are irregular and very infrequent) obviously daily contact (like fillings) allows the mercury toxins to build up and the body can't remove them (it takes the body a long time to drop them) and it builds up till it sends you mad and then kills you. The vapour is by far the worst (much worse than swallowing it since the digestive tract doesn't let mercury in very well) the lungs are more efficient at allowing mercury into the bloodstream. Mercury in it's elemental form though is much safer than it is in it's compound form. Stuff like Mercury Chloride and Mercurous chloride are absolutely deadly without question, one contact with stuff like that and you're as good as a gonner.
I heard of one sucidal guy who had decided to commit suicide by ingesting mercury, apparently it took him six months and a heck of alot of mercury to have the desired effects. Not recommended for instantanous death, but then again neither is cyanide which takes longer than you'd think and is absolutely brutal and is an agonising way to go.
