Have you ever noticed in the Bible this pitifully sad description of old age that King Solomon gave us 3000 years ago? He wrote, 

Don't let the excitement of being young cause you to forget about your Creator. Honor him in your youth before the evil years come--when you'll no longer enjoy living. It will be too late then to try to remember him when the sun and light and moon and stars are dim to your old eyes, and there is no silver lining left among your clouds [no doubt a reference to losing his hair]. For there will come a time when your limbs will tremble with age…and your teeth will be too few to do their work….Then let your lips be tightly closed while eating when your teeth are gone! …you will waken at dawn with the first note of the birds; but you yourself will be deaf and tuneless, with quavering voice.
