Doctor's orders! (part deux)

Doctors recommend us to live and behave as animals do - and ordinary people have ever said:

Tenez chauts les pieds et la teste;
Au demeurant, vivez en beste.

[ Keep feet and head warm:
Then live like the beasts.]

Michel de Montaigne - An apology for Raymond Sebond (Complete Essays II,12)

Drunkenness - recommended by doctors once a month

I have heard one of the best doctors in Paris, Silvius, state that it is a good thing once a month to arouse our stomachs by this excess so as to stop their powers from getting sluggish and to stimulate them in order to prevent their growing dull.

The medical system in Babylon

Next in ingenuity to the old marriage custom is their treatment of disease. They have no doctors, but bring their invalids out into the street, where anyone who comes along offers the sufferer advice on his complaint, either from personal experience or observation of a similar complaint in others. Anyone will stop by the sick man's side and suggest remedies which he has himself proved successful in whatever the trouble may be, or which he has known to succeed with other people. Nobody is allowed to pass a sick person in silence, but everyone must ask him what is the matter.
