This is all definitely off topic. But with apologies here goes. ><So how many times have we 're-cycled?' the drinking water> > >Wasn't there once a Scotsman who poured a bottle of Scotch over his friends >grave every year on the anniversary of his death?

Sea level is fairly unchanging. The oceans are well mixed or they would stagnate. So the residence time of a water molecule in the sea is on average 4000 years. In other words oceans renew themselves in only 4 millennia. Seems improbable? Ripley (Believe It Or Not) would be proud.
