I RETURNED to walking after a five month gap, the delay having come about on account of being a bit under the weather. Not me, you understand, but south west Scotland, which had spent much of the winter assailed by flooding and storms. Since I planned to go walking, not wading, I patiently waited this out until the first signs of impending spring brought calmer, warmer and — most importantly — drier weather. And then I got sunburnt. In Scotland. In March. It’s like my special super-power.
