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 ft., 
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 way too old."
