Here's a little story for you. My university in the US, American University, is in DC. My freshman year, there was a huge scandal in the district about lead contamination from pipes. My uni sent an e-mail out saying that they tested the water and it was safe to drink.
Well, my friend started to go bald that year. Which isn't that surprising since many people experience hair loss in their late teens/early twenties. But most of those people are men, and Nicole is a girl. Huge clumps came out at a time. So she went to the doctor and they ran some tests. The doctor came in and said, "um, Nicole, have you been working around heavy metals?"
She said no and, needless to say, they figured out that it was indeed the lead from the taps. Soon after my friend's father wrote a letter to the university, AU put filters on all the taps.
Anyway, I'm not sure why I told this story except it's the only slightly interesting one I can think of pertaining to the potability of university water supplies.
I had actually heard the thing about 111 in cricket. I'm not sure why i picked that number except that when I was a small child, I'd go through all my parent's books, open them to page 111 and read that page -- dooming me to a life of nerdom.
