The whole school of Salerno wrote for the English king:
If you want to be healthy, if you want to remain sound,
Take away your heavy cares, and refain from anger,
Be sparing of undiluted wine, eat little, get up
After eating fine food, avoid afternoon naps,
Do not retain your urine nor tightly compress your anus.
Do these things well, and you shall live along time.
Should you need physicians, these three doctors will suffice:
A joyful mind, rest and a moderate diet.
In the morning, upon rising, wash your hands and face with cold water;
Move around awhile and stretch your limbs;
Comb your hair and brush your teeth. These things
Relax your brain and other parts of your body.
After your bath keep warm; stand or walk around after a meal;
go slowly if you are of cool temperament.
Take a short afternoon nap, or none at all, as
Fever, indolence, headache and chest cold
May result from that nap.
Four illnesses came from gas retained in the stomach:
Spasm, dropsy, colic and vertigo.
Your stomach will suffer great harm after a heavy meal.
In order not to feel weighed down at night, make your evening meal
