Air pollution is the reason why I don't come to Poland in winter.
It was a horrific sight to see all the black coal smoke billowing out of the chimneys. Poles burn their garbage as well, plastic bottles etc.... Instead of paying a few zoltys for proper pick up. I understand some ppl aren't as fortunate and everyone needs heat. Cough,cough!
Another thing you wont see a lot of in Poland are elevators in apartment buildings. They have to walk up and down 10 flights of stairs each trip. I think they were built by the Commies.
If you need to lose some weight...There you go!
