When I was a kid, I used to believe that smoking "hurt" - that it burned your lips and lungs because you were breathing in really really hot air. This was after the first time I saw someone smoking - my eyes went really wide because I saw the person inhale, and saw the end of the cigarette burn bright red. I pointed and asked "Doesn't that hurt?" before being shushed by my mom.
