Most people these days are on one prescription drug or another. Americans are depressed, we have liver problems, need weight loss aids, have heart issues, experience chronic pain. Pharmaceuticals are in everyone’s home and no one ever thinks about how their prescriptions might affect another person. Prescriptions are personal; you’re not supposed to share them. But that’s exactly what you’re doing every time you drink water from the tap and you don’t even realize it.
Everyone knows THAT guy. You know the guy who spits his gum out of a moving car, regardless of where it may land. He’s the same guy who throws his empty beer cans into the gutters after crushing them on his head. He’s the same guy who dumps used motor oil into the sewers when he thinks no one is watching.
