Advance advertising for the weekend Guardian:

British teenagers drink, smoke, take more drugs and lose their virginity earlier than many of their parents believe, according to a unique Guardian/ICM poll.

As my 81-year-old mother advised me not so long ago, where one’s teenaged children are concerned, there are some questions it’s polite to leave unasked.
