Tears as Expression and Protection

All human beings cry. From the birth to the death, from the womb to the tomb, tears have become a part of people's lives. Babies cry for a variety of reasons: hunger, ear pain, physical hurt, indigestion, burns, and wetness. Children scream when they lose a fight. Sympathetic adults shed tears when touched by a tender scene. Some suitors become teary-eyed upon hearing the sweet sound of yes from the lady they are wooing. In moments of triumph, winners burst into tears of joy. When teased or scolded, sensitive individuals sob. The risk and broken-hearted cry out of pain and anguish. Others mourn the loss of their loved ones.

Tears are an expression or result of an intense emotion. But they are also an important part of the human body's protective mechanism. Tears are small drops of fluid secreted by two lachrymal glands located behind each of a person's eyelids. These glands squeeze out their salty solution through small ducts in the underside of the eyelids. Each time the eyelids blinks, it suck a little fluid from the glands. This fluid then bathes the cornea, the transparent front part of the eyeball's outer coat. Without the moisture provided by these fluids, the eyeball would rub so painfully on the inside lining of the eyelids. Tears also wash away foreign particles in the eye such as dust, hair, and other minute particles. When the eye is irritated tears overflow.Tears also contain proteins that help make our sight organ immune to infection. It also has a mild germicide called lysozyme that kill bacteria and other potentially harmful microbes.

Tears promote the health of our eyes. But their release also helps develop our emotional and social well-being. Children normally cry when afraid or hurt. It has been a tradition among many families to make boys ashamed of showing pain or fear. Since crying is considered unmanly, boys tend to repress and deny all kind of feelings, including tenderness. This impedes their ability to establish a wholesome relationship with family members, freinds, and fellow workers. Suppressed grief could also affect one's nervous system.

When a person experiences fervid emotion such as grief or great joy, the muscles around the lachrymal glands tighten up and squeeze copious tear fluids. So when you feel like crying allow yourself to cry. These lachrymal glands and tears stored in them are natural parts of human beings placed there for a purpose. They are to protect our eye and provide us a means of expressing our most intense emotions.

Loud Noise is Unhealthy

Some people may well tolerate loud noise but there are many reasons to stay away from it. Noise is one of human life's stressors. When a person exposed to loud noises, the blood vessels constrict and less blood flows to the organs. Noise is like passive smokers. People aren't aware that noise is affecting their health.Noise are unpleasant, annoying, and distracting sounds. Most kinds of noises are produced by vibrating objects that send out irregular vibrations at irregular intervals.

Dutch researchers also found out that people living on noisy streets suffer more high blood pressure than those in quieter areas. According to them, noise can cause people to get angry more easily, and provoke depression and organic diseases particularly when under stressful situations. Younger people are more at risk. It was reported that mothers who lived near airports bore more premature and underweight babies.

The researchers also agree that noise from traffic, night clubs, building firms, lively restaurants with videoke, discos and even background music- is enough to make some people's muscles tense, their pupils dilate, their heartbeat increase, their arteries constrict and their blood cholesterol and adrenalin levels rise. To much exposure to noise can also cause deafness.

Trichinosis Desease -Eating Undercooked Food

Trichina is a small round worm that causes the desease trichinosis. The worm is a parasite, it lives in and feeds on other animals. The Trichina infects human beings and other animals, especially hogs, bears, and rats. Trichinosis in hogs, bears, and rats usually results from eating infected meat and infected garbage. The larvae ( early form of the worms ) live in microscopic cysts ( sacs ) in the muscles of animals they infect. They usually live in the animal's chest and neck muscles. If an animal infected by the larvae is allowed to live, the cysts eventually harden and the larvae die. But sometimes infected animals are killed for meat. In such cases, the larvae can be killed by thoroughly cooking or freezing the meat. However, if the larvae are not killed and the meat is eaten, the larvae are freed from the cysts during digestion. The larvae attach themselves to the intestine of the person who eats the meat. They become adult worm in about 3 or 4 days. The largest are only about 6 millimeters long. It is difficult to know how widespread trichinosis is because symptoms are similar to other less severe ailments, and the tiny worms which cause the problem can usually be detected only by careful body tissue examination.

Trichinosis has long been associated with eating undercooked pork and other swine products. Spread by butchered animal wastes and rats, virtually any animal eating such materials can carry the worms and be a source for human infection. Trichinosis is not true infection since the worms do not multiply in the body. Besides pigs, common sources of trichinosis are bear, walrus, whale seal, and dogs and cats when used for food. Europeans have contracted trichinosis from eating horsemeat, a new known source of the desease.

Although trichinosis is not usually fatal, a person eating heavily infested, undercooked meat can die. Aching muscles are usually the first indication of trouble. The pains generally start in the shoulders, then spread to the back and legs. A loss of appetite, nausea, and vomiting follow. Since the tiny worms can plug up vessels carrying lymph fluid in the body, a typical symptom is swelling of the tissues around the eyes. Almost certain diagnosis can be made when the three symptoms- muscles pains, loss of appetite or nausea, and swelling around the eyes- occur together.

To avoid ingesting the worms, take special precautions when eating meat from wild animals, such as wild pig and bear. Pork products, especially sausage, should be well-cooked.

Preventing trichinosis is a relatively simple procedure:

1. Thoroughly cook all animal flesh before eating, especially pork. People using microwave ovens should be careful that all the meat reaches the minimum cooking temperature (140 degrees ) . Trichinosis has resulted from "cold spots" in the meat when using microwaves.

2. Freeze pork and pork products for at least three days at- 16.6 degrees F to kill the worms. Even lower temperatures may be needed to kill some cold-resistant worms found in artic regions.

3. Cook all garbage fed to pigs to prevent worm spreading.
