As for ancient Greek medicine, in order to stay healthy we should keep an eye on:
– Light and Air (aer)
– Food and Drink (cibus et potus)
– Exercise and Rest (motus et quies)
– Sleep and Wakefulness (somnus et vigilia)
– Retention and Evacuation of wastes (secreta et excreta)
– Perturbations of the mind and Emotions (affectus animi)
