Hi Ivan.
I have lived by the sea in NZ, up the mountains here in Aus, nnnnnow wwwe live near the Southern Alps and it's Blo*^%y freezing in the winter, but the air is so clean it hurts to breath ha ha. The people here live to thier late 90s to over a 100, and not a skerrick of pollution to be seen in the sky, my wife calls Cooma, Australia's Brigadoon.
Cheers Des
