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.

Shakespeare.
