A human body in no way resembles those that were born for ravenousness; it hath no hawk's bill, no sharp talon, no roughness of teeth, no such strength of stomach or heat of digestion, as can be sufficient to convert or alter such heavy and fleshy fare.
PlutarchWhen a man's eyes are sore his friends do not let him finger them, however much he wishes to, nor do they themselves touch the inflammation: But a man sunk in grief suffers every chance comer to stir and augment his affliction like a running sore; and by reason of the fingering and consequent irritation it hardens into a serious and intractable evil.
Plutarch
