Famous quotes containing the words variations and/or age:

“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)

“When winter snows upon thy sable hairs,
And frost of age hath nipped thy beauties near;
When dark shall seem thy day that never clears,
And all lies withered that was held so dear,
Then take this picture which I here present thee,
Limned with a pencil not all unworthy;”
—Samuel Daniel (1562–1619)
