An elderly gentleman has just emerged from a swim in the cold waters off Paignton, the seaside town in Devon, south-west England. Still to towel himself down, he looks chilled to the bone but stands talking to friends out of view. The man wears dark trunks (costume) and has a large belly but otherwise looks fit and healthy, a true picture of health for a man of his age, after swimming in these seas for many years and enjoying the endorphins that are stimulated after wild, outdoor swims.
