Thank you all, and Karen and lilith Cherry for your re-assurance, oh i know China is very civilised lol, but i worry about the things like bird flue, typhoid etc, i don't think he has time to have any vaccinations, which are not compulsory but are advised, i am a typical mother,worry, worry, worry about everything and anything lol.

I am glad the pollution is not as bad as i thought and yes i did think they would be cleaning the city up for the olympics,so that is all good, as for the smoking, i hate to tell you this but my son is a smoker, i so wish he wasn't , so bad for his asthma, he came from a non-smoking home, but got addicted to it,he started with his peers at about 16 and we are hoping he will try and give it up once and for all, he talks about it, but so far no result,no-one apart from him in my family smokes.

Yes i am sure it will be a very tiring, but exciting trip for him,he probably will be flying out this sunday, if all goes according to plan, hopefully his visa will be through and away he goes.
