A diet of green cheese, onions, coarse bread, buttermilk or mild ale (cider on special occasions)kept Thomas healthy. Perhaps the secret of his longevity, was simply a diet of rancid cheese, coarse hard bread, and small drink, generally whey.
His recipe for long life was reputed to be
"Keep your head cool by temperance and your feet warm by exercise. Rise early, go soon to bed, and if you want to grow fat [prosperous] keep your eyes open and your mouth shut".
He never smoked or needed medicine and was never examined by a doctor, until after his death when the scientist and physician, William Harvey, examined his body and declared all his organs to be perfectly healthy.
