"Even our very breath teaches us moderation; when walking we catch the smell of  a fresh mown lawn, and we tarry to drink it in. We may say, I think I'll spend an hour here enjoying this smell, only to find that after a minute or two the fragrance diminishes. We may think that something's wrong with our nose, but then we catch the scent of the lilac and learn that moderation brings joy but to overindulge is to lose." Author unknown.
