Ὁ βίος βραχύς, ἡ δὲ τέχνη μακρή, ὁ δὲ καιρὸς ὀξύς, ἡ δὲ πεῖρα σφαλερή, ἡ δὲ κρίσις χαλεπή.

Ho bíos brakhús, hē dè tékhnē makrḗ, ho dè kairòs oxús, hē dè peîra sphalerḗ, hē dè krísis khalepḗ.

Life is short, and craft long, opportunity fleeting, experimentations perilous, and judgment difficult.

—Aphorisms of Hippocrates
