In an American history discussion group, the professor was
trying to explain how societies ideal of beauty changes with
time. "For example, he said, "take the 1921 Miss America.
She stood five feet, one inch tall, weighed 108 pounds and
had measurements of 30-25-32. How do you think she'd do in
today's version of the contest?"

The class fell silent for a moment. Then one student piped
up, "Not very well."

"Why is that?" Asked the professor.

"For one thing," the student pointed out, "She'd be about
a hundred years old."
