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)
“If you don’t begin to be a revolutionist at the age of twenty, then at fifty you will be a most impossible old fossil. If you are a red revolutionary at the age of twenty, you have some chance of being up-to-date when you are forty!”
—George Bernard Shaw (1856–1950)
