Yes you are a bit of a health Nazi arn't you. There is a time and a place to fight battles, and that wasn't it. Really good psychology to make a woman feel guilty about giving her children asthma when she is about to leave them to go into hospital. And you are wrong; smoking sure as hell does not help asthama but it is unlikely that it causes it de novo in someone who is not already prone to it. And then you say, "Luckily the ambulance crew turned up before I could tell her that the best thing she could do was die quickly of lung cancer so her kids might get adopted into a family that may have the slightest concern for their health." Is that supposed to be funny? I think not. You are beginning to come over as a bit of a sententious prick, if I may be so bold
