At the door to 2021, when the year ahead held no prospect beyond two AstraZeneca jabs, I made a series of New Year’s resolutions here on the farm in East Anglia, from trying to be outside at sunrise and sunset—which helps the body’s natural circadian rhythm—to turning off the shower when applying shampoo or shower gel. I soon learned that being outdoors for sunrise in January at 8am, and again in the afternoon at a time when civilised society typically “takes tea,” was a lot easier than a boot camp reveille in mid-June at 4.40am, when even dairy farmers are bleary-eyed and semi-dormant.
