Art is born of the observation and investigation of nature. - Cicero

We must stand up against old age and make up for its drawbacks by taking pains. We must fight it as we should an illness. We must look after our health, use moderate exercise, take just enough food and drink to recruit, but not to overload, our strength. Nor is it the body alone that must be supported, but the intellect and soul much more.

It is the peculiar quality of a fool to perceive the faults of others and to forget his own.

Angosciarsi profondamente per le proprie disgrazie non è proprio di chi ama l'amico ma se stesso.
