When I went to the doctor recently, they asked me the usual questions about do I smoke, how much do I drink etc. But they also asked me if I have a gambling problem, which is strange, because I don't gamble at all.

But it seems that, as a result of this fishing expedition, the NHS has uncovered a hidden gambling problem in this country. It has responded by opening more clinics to treat problem gamblers. I wonder how many porn addicts they would find, if they did a similar exercise for porn addiction?
