Straight from the horses mouth

“What is the difference between youth and age?” asked the rider.

“In youth,” said the horse, “we cannot discriminate between knowledge and wisdom.

In old age we can.”“As I get older,” said the rider “I find I become less tolerant.”

“As I get older,” said the horse “I can distinguish between the things I should tolerate and the things I should not.”
