I have been drinking most of my fluids from either glass, ceramic, stainless steel cups or a stainless steel thermos as of late. I saw an article out of Europe regarding "load testing" studies conducted on toddlers' who have been discovered to be full of all sorts of plastic, rubber and metals due to the materials of their toys and those important delivery systems such as plastic bottles, diapers, rubber nipples and polyvinyl teething toys.
Hence, my decision to drink liquids via more organic means has made my water taste better, and fewer; hopefully fewer, PVCs entering my body. Swimming in chlorine; (a nasty biocide), 3-5 days is bad enough.
This ad from DDB in San Francisco and art directed by a talented guy named Dustin Smith reminded me why plastic is really bad for you
