Eat Oysters - Love Longer
Christopher Kerrison , ex-racing driver and stockbroker's clerk, withdrew from the City rat race to a cottage overlooking the Essex marshes.
In 1963 sub-zero temperatures froze the River Colne and killed 95 per cent of Colchester's famous oysters.
Knowing nothing of the skills required, Kerrison took over a new lease of the ancient fishery and began an 18-hour day restoring the oyster beds, delivering to London before 7.0 am, working on the water till evening, then falling asleep at night doing his office work.
Today he is the largest, most successful oyster cultivator and exporter in Britain.
