How can we get rid of garbage? Do we have enough energy sources to meet our future energy needs?These are two important questions that many people are asking today. Some people think that man might be able to solve both problems at the same time. They suggest using garbage as an energy source, and at the same time it can save the land to hold garbage. For a long time, people buried garbage or dumped it on empty land. Now, empty land is scarce. But more and more garbage is produced each year. However, garbage can be a good fuel to use. The things in garbage do not look like coal, petroleum, or natural gas; but they are chemically similar to these fossil fuels. As we use up our fossil-fuel supplies, we might be able to use garbage as an energy source. Burning garbage is not a new idea. Some cities in Europe and the United States have been burning garbage for years. The heat that is produced by burning garbage is used to boil water. The steam that is produced is used to make electricity or to heat nearby buildings. In Paris, France, some power plants burn almost 2 million metric tons of the cities garbage each year. The amount of energy produced is about the same as would be produced by burning almost a half million barrels of oil.Our fossil fuel supplies are limited. Burning garbage might be one kind of energy source that we can use to help meet our energy needs. This method could also reduce the amount if garbage piling up on the earth.

The thought of not sleeping for twenty-four hours or more is not a pleasant one for most people. The amount of sleep that each person needs varies. In general, each of us needs about eight hours of sleep each day to keep our bodies healthy and happy. Some people, however, can get by just a few hours of sleep at night.It doesn't matter when or how much a person sleeps. But everyone needs some rest to stay alive. Few doctors would have thought that there might be an exception on this. Sleep is, after all, a very basic need. But a man named A1 Herpin turned out to be a real exception, for supposedly, he never slept!A1 Herpin was 90 years old when doctors came to his home in New Jersey. They hoped to negate the claims that he never slept. But they were surprised. Though they watched him every hour of the day, they never saw Herpin sleeping. He did not even own a bed. He never needed one.The closest that Herpin came to resting was to sit in a rocking chair and read a half dozen newspapers. His doctors were baffled by this strange case of permanent insomnia. Herpin offered the only clue to his condition. He remembered some talk about his mother having been injured several days before he had been born. Herpin died at the age of 94, never having slept a wink.

Americans are well known for the strange diets they always seem to be following. It seems that Americans like to diet almost as much as they like to eat. New types of diet plans are always coming out. Usually, though, they don't stay popular for long.There are many diets on the market. It is often difficult to know which ones really work. It's also hard to believe how fast a dieter is supposed to shed pounds. A lot has been written about dieting. And some interesting facts about diets and foods have been discovered.For example, did you know that the more celery you eat, the more weight you will lose.9 Celery has "negative" calories. The body burns up more calories digesting a piece of celery than there are in the celery stick itself.Dieters shun potatoes because they think they are fattening. But they aren't. A potato has about the same number of calories as an apple. To gain a single pound, you would have to eat eleven pounds of potatoes!Some dieters even worry about getting fat from licking postage stamps. But they have nothing to worry about. The glue on an average stamp has only about one-tenth of a calorie. Maybe a diet of postage stamps would be popular?
