The problem, JimmyBobby, is defining where behavior becomes "purely private". We are defining more of our lives as "not private" with every new regulation and law. It wouldn't take much of a stretch to define everything we do as affecting someone else, or society at large. There are those who think we watch too much TV for our own good, and that it contributes to a sedentary lifestyle. Do we want the government to regulate how much TV we can watch? Or how much musis we listen to? Or how much time we spend reading? Reading, after all, is a sedentary activity, and reading the "wrong" books could put bad ideas into our heads, and make us not want to obey the government experts who know so much better than we do what is best for us.

This is one slippery slope that I will not go down for anything.
