When Pomponius Atticus [a friend of Cicero] fell ill, and medical attempts to prolong his existence merely prolonged his pain, he decided that the best solution was to starve himself to death. No need to petition a court in those days, citing the terminal deterioration in your ‘quality of life’: Atticus, being a Free Ancient. merely informed his friends and family of his intention, then refused food and waited for the end. In this, he was much confounded. Miraculously, abstinence turned out to be the best cure for his (unnamed) condition; and soon the sick man was undeniably on the mend.
There was much rejoicing and feasting; perhaps the doctors even withdrew their bills. But Atticus interrupted the merriment. Since we must all die one day, he announced, and since I have already made such fine strides in that direction, I have no desire to turn around now, only to start again another time. And so, to the admiring dismay of those around him, Atticus continued to refuse food and went to his exemplary death.
