.... The second is characterized by brain waves getting larger. The third and fourth stages are where the sleeper is in a deep sleep in which their brain waves are huge and slow which makes this stage the hardest to wake from. After an hour or so, you shift into a highly active stage characterized by rapid eye movements, hence the name REM sleep. Suddenly your brain waves are almost the same as if you were awake. You're in the dreaming stage, which occurs several times across the course of the night. Now, what happens when we're deprived of the restful sleep we need? We're less alert and attentive, more inclined to irritability and other moo .....

.... about , but things soon became clearer, although not all is still known. When it was first discovered researchers had named it the T-lymphotropic virus, type III ( HTLV-III ), but later they renamed it HIV-1 because several more forms were discovered. After the virus enters the bloodstream, it destroys white blood cells ( T-lymphocytes). Since they play a big role in the immune system, their presence is very damaging. also infects another part of the immune system. Once the virus gets to the macrophages, it doesn't destroy them, but instead it stores it there. Later the macrophages carry the virus to other vital systems. Early detection is a key .....

.... of these pregnancies are unwanted or unplanned. Half of the unmarried teens who get pregnant do so within six months of their first sexual experience. In fact, between 1986 and 1990, teen childbearing increased by 16 percent. What’s worse, pregnant teenagers often don’t see a doctor until the time of delivery. Another serious problem surrounding teen sexual intercourse is the probability of AIDS and sexually transmitted diseases (STDs). Each year, three million teens are infected with STDs. Among 14- to 20-year-olds, chlamydia is the most common. It has no obvious symptoms, and can cause infertility if left untreated. Another common dise .....

.... is wrong. No one wants to be blamed for someone’s death, so people believe passive euthanasia is acceptable because the doctor is not actually killing the patient. People believe that a doctor should not play God and make decisions concerning someone else’s life. What happens if a cure is found for the disease? The sick person died for no good reason. What if the patient gets better? If they are killed then they have no chance to get better. According to the American Medical Associates doctrine that was adopted, killing someone is wrong but letting someone die is allowed. The American Medical Association’s doctrine should sanction act .....

The effects can be quite different depending on the amount of the drug consumed and the circumstances under which it is taken.

.... would seek to protect the human who is still to small to cry aloud for it's own protection, have been accused of having a 19th Century approach to life in the last third of the 20th Century. But who in reality is using arguments of a bygone Century? It is an incontrovertible fact of biological science - Make no Mistake - that from the moment of conception, a new human life has been created. Only those who allow their emotional passion to overide their knowledge, can deny it: only those who are irrational or ignorant of science, doubt that when a human sperm fertilizes a human ovum a new human being is created. A new human being who carries .....

.... (or what the individual considers trivial.) Furthermore, patients with benign forgetfulness usually can remember what was forgotten by utilizing a number of subterfuges, such as writing lists or notes to themselves and leaving them in conspicuous places (Horton and Smart, 1984, p. 320). Individuals with benign forgetfulness also are acutely aware of their memory deficit, while those with dementia - except for in the early stages of the disease - have no insight into their memory deficit and often blame others for their problems. In addition to the memory deficit interfering with the patient's daily activities, patients with demen .....

.... or handicaps. It come from the Greek words for 'good' and 'death', and is commonly called mercy killing. Voluntary euthanasia may occur when incurably ill persons ask their physician, friend or relative , to put them to death. The patients or their relatives may ask a doctor to withhold treatment and let them die. Many critics of the medical profession contend that too often doctors play god on operating tables and in recovery rooms. They argue that no doctor should be allowed to decide who lives and who dies. The issue of euthanasia is having a tremendous impact on medicine in the United States today. It was only in the nineteenth cen .....

.... general types of A. D. D., the stereotypical, high-energy, hyperactive group, and the less known underactive ones that often daydream and are never mentally present anywhere. Typically, people with A. D. D. are very likable and are usually very emphatic, intuitive, and compassionate, however they have very unstable moods that can range from an extreme high to an extreme low instantly, for no apparent reason. Usually, they procrastinate often and have trouble finishing projects, while conversely, they can hyperfocus at times and accomplish tasks more quickly and efficiently than a normal person could. Often they have short tempers and lack the impul .....

.... Others cry frequently and have irregular sleeping and waking cycles. These differences seem to be due to heredity, but such factors as the mother's nourishment while she carried the child before birth may be important. An obvious biological difference exists between boys and girls. Later, as children grow and develop, sex differences become stronger. Certain glands called endocrine have different physical effects on boys than on girls. These effects, in turn, produce different psychological experiences in the sexes. But male-female differences in personality are not due solely to biology. The environment is equally important. Society t .....
