Warning conspiracy theorist alert
I am just going off a public announcement in my local area that traces of cryptosporidium has been found in the water and residents of numerous towns and cities are being advised to boil their water before drinking. I've never heard of cryptosporidium before as most wouldn't, but a conspiracy theorist might go nuts for the, 'crypto', part of the word. However, just a mere observation on my part.
Seriously though, public notices about drinking water needing to be boiled before drinking, preparing food or even brushing your teeth with. This is the kind of thing that old people say to their grandchildren when they are telling them how much better things are for them than they used to be for them, and this is in the UK.... If they survive.
