We know that the body needs food in order to function well. However, many people fast at some time during their lives. Why is this?Some people fast for political reasons. In the early 20th century, women in England and the United States weren39。s instruments. And strangely enough, there was food on the table. Where was everyone? Did the crew jump from the Marie Celeste? Or did something e up from the ocean and take the captain and crew away?The captain of the Dei Gratia looked around for clues.

Instead, some scientists now think gas from the center of the earth caused the explosion.Scientists continue to travel to the Tunguska plateau looking for clues to the cause of the explosion. Every few years newspapers report that scientists finally have a solution to the Tunguska。t burned.Over the years, there were many explanations for the Tunguska explosion. Some people thought it was a huge bomb. Others suggested that it was an exploding spaceship. One recent theory is that the meteor exploded in the air before it hit the ground. That explains the missing crater, but it doesn39。t enough grain for future crops. Their leader, Captain White, decided to sail back to England to get supplies. However, there was a war in Europe, and three years passed before he returned to North America.When Captain White came back to Roanoke in 1590, he was eager to see the settlers. He looked out from his ship, but no one was there to meet him. There were no signs of life. The settlement was deserted.No one knows why the Roanoke settlers disappeared.

Many Hindus fast on special occasions, as do some Christians and Buddhists.Of course, not everyone fasts for political or religious reasons. Some people occasionally fast just because it makes them feel better. The American writer Mark Twain thought fasting was the best medicine for mon illnesses. Whenever he had a cold or a fever, he stopped eating pletely. He said that this always made his cold or fever go away. Another American writer, Upton Sinclair, discovered fasting after years of overeating, indigestion, and headaches. His first fast lasted for 12 days. During this time, his headaches and stomachaches went away. Sinclair said that fasting also made him more alert and energetic.Choosing to go without food can be very dangerous.

In fact, the Emperor of Japan is not allowed to touch it. Why? Well, the insides of the puffer fish are very poisonous. They contain a poison 275 times more powerful than the deadly poison cyanide.Usually nothing bad happens when fugu is on a restaurant39。s also true that quite a few Olympic athletes had to overe illnesses early in their lives.One excellent example is Wilma Rudolph.
