Thanks Doreen,

What you say makes very good sense. While having clean drinking water and proper sewage treatment is something we take for granted, it is not something we lay people immediately think of.

It made me think - the older generation of my family (those born in the 1890's-1910's lived to be well into their 90's, but that the younger folks in the family only made it to their 70's. And most of those died from complications of diabetes and heart disease. I can remember my very forth rite great-great-aunt saying "That's stuff is not realy food!" As a youngster I would always cringe at her butter, fatty meats etc. The lady did live to 97... she was definately on to something!

It just goes to prove that things aren't always black and white, that there are many shades of grey. (ie. many contributing factors) to every situation.
