W: Professor Smith, last time we talked about third-hand smoke. Can you say more about it?M: Of course, we know that breathing in other people's smoke is nearly as unhealthy assmoking on our own.W: So when I enter a car or a building where people have been smoking, is that bad news?M: Yes, it is potentially bad news to you.W: But why?
