A few years ago, during some kind of UK water panic, I overhead the following conversation in the supermarket.
First woman:-(addressing friend with a trolley full of bottled water)
"What have you bought all that for?"
Second woman:- "Well you never know, and you can't be without water"
First woman:- "But we live in Malvern!"
Malvern is a Spa town with literally dozens of freely available fresh springs of proverbially pure water. It was, until very recently, bottled and sold worldwide as Malvern Water, by Coca Cola. The springs have never been known to run dry.
I don't think reason has anything to do with the topic!
Cheers
