So about 150 people in each country were questioned and around about 50 (or less) of them drank to improve their chances.
So the headline is kind of wrong it should be "a minority of Europeans get drunk to increase their chance to have sex'"
Obviously putting a little truth from the article into the headline doesn't sound so good but .......
..... I love this time of thing, its such a load of C**P and just typical of the BBC these days to publish such rubbish but it takes the edge off the more depressing real stuff - maybe that's why they publish it
