It's a times like that I think of the statistic that water in some big
cities has passed several times through people's kidneys before finding
its
way to the sea to go though the normal evaporation/rainfall cycle. I
forget
how many times it is...

I thought it was 7 for some reason?

Bet that's a bogus number given that most of the water going
thru a particular house doesn't go thru anyone's kidneys, it just
goes into the bath or shower and down the drain etc.
