An ounce of prevention is worth a pound of cure. Early to bed and early to rise, makes a man healthy, wealthy and wise. Stuff a cold and starve a fever. An apple a day keeps the doctor away. Prevention is better than a post-mortem.
Prevention is more important than attempting a cure - afterwards.
An ounce of experience is better than a pound of science. Early to bed, early to rise and your girl goes out with the other guys. Early to bed and early to rise makes a man tired. An onion a day keeps the world away. A pill a day keeps the stork away.
