In my daily blog reading, Aaronovitch has useful advice on dieting. He's losing slower than our mayor, but then our mayor is a loser. Stephen Pentz has some musical commentary I agree with.
For instance, I am willing to acknowledge (albeit reluctantly) that people are entitled to believe that "Imagine" is John Lennon's best song, and that it provides a possible blueprint for reality. (I, on the other hand, would opt for "You've Got to Hide Your Love Away," "If I Fell," or a dozen or so other of his songs.)
