Why I subscribe to "New Scientist"

From the "Feedback" column in the 8 April 2006 issue:

A choice paper title discovered by Samantha Bell in the course of her work for a journal of respiratory medicine is "Didgeridoo playing as alternative treatment for obstructive sleep apnea syndrome: randomised controlled trial" (BMJ, vol 332, p.266). We are puzzled, though. It is usual in such trials to use placebos in control groups for the purposes of comparison. We have tried and failed to imagine what a placebo didgeridoo looks like, or for that matter sounds like.
