smoking vs. picking your nose

I have been in WV/Ohio for a week now and I have not posted anything because where I am staying has no internet access. It also is laking a T.V. so I have been reading. A lot. That said, I had to drive 20 minuets just to get internet service so I could write this blog.
I have noticed that EVERYONE here is a smoker and I can't remember living anywhere that people did not know it was a bad habit. In Houston the majority of the population was heath conscious and AZ and UT the majority was mormon. The last place I lived that had such a high smoker population was China. So I was thinking that watching all of these people do something so gross and nasty is like watching them pick their nose in public. It's just so wrong. Anyone with half a brain knows it's going kill you and it's not like cigarettes are the cheapest things in the world to buy. So how is it that they can afford them but at the same time be too poor to put glass in the windows of their house so they just slap up a pice of plywood. I just don't understand the desire to pick your nose in public.
