We discussed this in one of the meetings I worked last week. Isn't there chlorine in our drinking water? It really can't be that bad for us, can it?
Now, if I can only find info on eating too many carrots and your hands turning orange. My colleagues that I ate lunch with always laughed at me until they actually looked at my hands and they had a more orange tint than everyone else's. I eat a good 3-4 pounds of carrots weekly and don't plan on changing till I turn into a carrot ;)
