Mr. Johnson looked up at the sky. It was clear as far as the eye could see, except for the cruel sun. The insatiable sun drained the land of all moisture. He cursed the sun. Mr. Johnson ran his fingers through one of the rows of dirt and grabbed a handful. It was bone dry, almost powdery. He let the dirt sift through his fingers and it turned to dust in the wind. Mr. Johnson put his hands on his hips and surveyed the field. It was well seeded, that he knew. He seeded it himself, yet nothing sprang from the dirt. "Well, there's only one thing left to do," he said to himself. Mr. Johnson headed to church.

It is said that the first football helmet was used in a game between the Army and Navy in 1893. It was made of leather and put together by a shoemaker near Annapolis, Maryland. Soon, padded leather was used to improve them. These early helmets looked like those worn by pilots of the day.

In the early days of football, some players chose to wear helmets, but they were not forced to until it became a rule in college football in 1939. The National Football League (NFL) did not have a helmet rule until 1943.

Over time, football helmets became even more advanced. Starting in 1940, plastic was used to make the helmets. In 1955, a metal bar was placed in the front of the helmets to protect the player’s face. That idea of the single bar became the basis for the type of facemasks that we see on modern helmets today.

Before the 1800's people didn't have right or left shoes. They had shoes of just one shape that they used for both feet. When people first saw right and left shoes, they laughed. They called them "crooked shoes." "What a silly idea," they said.

The toothbrush as we know it today was not invented until 1938. However, early forms of the toothbrush have been in existence since 3000 BC. Ancient civilizations used a "chew stick," which was a thin twig with a frayed end. These 'chew sticks' were rubbed against the teeth. The bristle toothbrush, similar to the type used today, was not invented until 1498 in China. The bristles were actually the stiff, coarse hairs taken from the back of a hog's neck and attached to handles made of bone or bamboo. Boar bristles were used until 1938, when nylon bristles were introduced by Dupont de Nemours. The first nylon toothbrush was called Doctor West's Miracle Toothbrush. Later, Americans were influenced by the disciplined hygiene habits of soldiers from World War II. They became increasingly concerned with the practice of good oral hygiene and quickly adopted the nylon toothbrush.
