 If you eat using a fork, you are participating in a tradition that goes
 back thousands of years. Originally, forks were used for cooking in
 ancient Egypt. Over several hundred years, people began using them
 for eating as well. First, forks were used by kings and queens.
 Gradually, their use spread through Europe. Some people criticized the
 fork as being silly. After all, they said, people had fingers, which were
 easier to use for eating. Still, by the 1700s, forks were common all
 across Europe.
