In this part of the world, spring means finally getting to venture out of doors, after a dark and relatively cold, remorselessly grey, winter. I’m not sure what came over me this spring but having thought about it for many years—like that online course in financial management from the London School of Economics that I still haven’t signed up for—I actually did buy myself a pair of underwater, or at least waterproof, earphones for swimming. Before now I’d somehow failed to get the job done—too many other pressing issues. Who really needs waterproof headphones for the pool? Who needs Debussy while doing the Australian crawl?
