One more example of what free availability of data about human activities can produce!
A water utility company in Canada published the above graph, comparing the consumption of water of 27th and 28th February. Why every Canadian flushed the water together on the 27th February?
Well, it seems 80% of Canadians were watching last Sunday’s gold medal Olympic hockey game.
And they’d all go pee between periods.
It is amazing how water consumption correlates with the game!
