Old age is the harbor of all ills. - Bion of Borysthenes

It hurts the bald-head just as much as the thatched-head to have his hairs plucked.

Just as the good actor perform well whatever role the poet assigns, so too must the good man perform whatever Fortune assigns. For she, says Bion, just like a poet, sometimes assigns the leading role, sometimes that of the supporting role; sometimes that of a king, sometimes that of a beggar. Do not, therefore, being a supporting actor, desire the role of the lead.

Boys throw stones at frogs in fun, but the frogs do not die in fun, but in earnest.
