Apparently the aluminum/alzheimers/breast cancer scam originated with anti-perspirant because it contains aluminum chloride. So, apparently deodorant is (supposedly) safer.
But as for the Nalgene thing, well...*takes a drag from a cigarette* I'm really not too concerned about the whole health aspects of it. Nearly everything on the consumer market is bad for you these days. The solution? Everything in moderation, including moderation.

PS: I'd also like to add that the Nalgene estrogen bit only includes their Lexan bottles, and not the standard HDPE variety, the very same material that army canteens are made of.
