Iswim for my health. Not just my mental health, but my physical health too. It is, of course, all part of the same piece. In summer, swimming in the sea near my home in Brighton is my primary means of ensuring I stay physically fit. Some days it’ll be a light back and forth of breast stroke as the sun goes down. Others it will be a snappy front crawl out and round the yellow ‘Swim Area’ buoys which are tacked out along the coast here from May until September.
