Crabbed age and youth cannot live together:
Youth is full of pleasance, age is full of care;
Youth like summer morn, age like winter weather;
Youth like summer brave, age like winter bare.
Youth is full of sport, age’s breath is short;
Youth is nimble, age is lame;
Youth is hot and bold, age is weak and cold;
Youth is wild and age is tame.
Age, I do abhor thee; youth, I do adore thee:
O my love, my love is young!
Age, I do defy thee. O sweet shepherd, hie thee,
For methinks thou says too long.

(Passionate Pilgrim 12)

Lovers and madmen have such seething brains,
Such shaping fantasies, that apprehend
More than cool reason ever comprehends.
The lunatic, the lover, and the poet
Are of imagination all compact.

(Midsummer Night’s Dream)

A dangerous and lascivious boy, who is a whale
To virginity, and devours up all the fry it finds.

(All’s Well That Ends Well)
