[Margaret Pilkington]

I have never smoked......I have often suggested to people that their health would be better(as well as their wallet) if they gave up smoking.....it was part of my job in pre-operative assessment(way back when)....but if the smoker doesn't want to quit then you only harden their attitude.

Most people who smoke are not daft. They know it isn't good for their health........most of them have tried to give up and failed. Some of them enjoy their cigarettes(though, for the life of me I cannot fathom out why).
The government say that smoking in parks is a bad example to children......personally I think this argument is very weak. Children see parents smoking......some of them will take up the fags...some of them won't.

It is no good saying something is banned in the public places in London if there is no-one to police the ban.
