Interesting point JJ.
Especially what you say about asthma and the like - my mum smoked throughout her pregnancy with me and I am generally fit and healthy with no breathing related allergies whatsoever (infact my only allergies are to medicines - aspirin and penicillin). By the time she got pregnant with my lil bro, she had given up smoking completely - and he is the most allergic person (with the exception of Cloudy
) that I have ever come across. He gets asthma, eczema, food and medicine allergies. He's a lot better off these days since he went vegan because fruit and veg are about the only things that *don't* set him off!
