This is a dangerous world we live in．The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, etc．You know this because you have heard all the statistics on the news and in the paper． But do you really have an accurate idea what they mean? The numbers are growing up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little．

   This growing trend of reporting only part of the information is becoming dangerous．For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide．This chemical, found in most cancerous tumors（肿瘤）, is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once．After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth．The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background．

   The point of this article is that one should be aware of what is and is not being said．When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths．Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view．For example, look again at the statistics that suggest skiing is safe．Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really the most dangerous? If you think about it, you realize far fewer people go skiing each year than the number of people who are in danger of a lightning strike．When you think about it, skiing is more dangerous than you might at first think when looking at statistics．If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s．To be warned is to be prepared．

It doesn’t matter when or how much a person sleeps, but everyone needs some rest to stay alive. That’s what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true? The doctors decided to see this strange man themselves.

    Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.

    The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by his strange continuous sleeplessness. They asked him a lot of questions, hoping to find an answer. They found only one answer that might explain this question. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason? No one could be sure.
