The oldest footwear of any kind ever found are sandals made of plant material. Scientists believe sandals found in the Arnold Research Cave in the American state of Missouri are about seven thousand five hundred years old.
That makes them about two thousand years older than the leather shoe found in Armenia.

FAITH LAPIDUS: Finally, old age does not sound exciting to most people. But a recent study offers good news for older adults.
It found that people become happier and experience less worry after they reach the age of fifty. In fact, by age eighty-five, people are happier with their life than when they are eighteen years old.
The findings came from a study of more than three hundred forty thousand adults living in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At the time, the adults were between the ages of eighteen and eighty-five years old.
BOB DOUGHTY: The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional tension -- better known as stress.
Arthur Stone was a leader of the study. He works for the Department of Psychiatry and Behavioral Science at Stony Brook University in New York. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The study found that stress levels dropped sharply after people reached their fifties.
