TUGAS - TUGAS (TASK 1-3)

TASK 1

My band is my hobby

The things what I like in the world is my hobby, playing music with my group. I think playing music can make our brain stabil, between the right and the left brain, also I can feel relax, and of course it very fun for me. My music group or we can call it ‘band’, the name of my band is The Reject. At present my band wanna be famous, because yesterday at the moment of Petroleiron closing ceremony we on the one stage with the one famous band in Indonesia, Naif. It is very amazing experience for us. Surely, I love my hobby, I love my band.


TASK 2
Why Do We Explore Space?

Why should mankind explore space? Why should money, time and effort be spent exploring, investigating and researching something with so few benefits? Why should resources be spent on space rather than on conditions and people on Earth, or in our own country.
Perhaps the best answer lies in our genetic make up. What drove our distant ancestors to move from the trees into the plains? Was it the lack of skills to compete in one ecological niche? If so, the adaptations selected for after the move have resulted in a species expanding into all possible areas and environments. The drive to spread genetic material and ensure the success of not just the species, but of one type of genetic
material. The wider the distribution of a species, the better the chance of survival.
Culturally nearly every successful civilization has been willing to explore. In exploring, dangers of surrounding areas may be learned and prepared for. Dangers may be political enemies in neighboring cultures, physical features of the area, a change in the area which might effect food supplies or any other number of factors. All pose a real danger and all may be made less dangerous if certain preparations are made. Without knowledge, the danger may strike and completely destroy. With knowledge, the effects or consequences may be lessened.
Exploration also allows resources to be located. Resources translate into power and success at survival. Whether the success be financial, political or genetic additional resources are always a boon when used wisely. In any of the three manners, use of resources allows a heightened percentage for survival. If the resources have no immediate need, then perhaps later the resources will be used.
Resources may be more than physical assets. Knowledge or techniques acquired in exploring or preparing to explore always filter from the developers to the general populace. Techniques may be medical applications, uses for drugs or ways of living to increase the quantity of time lived or the quality of that time. Techniques may be social, allowing the people in a society to better understand those within or outside the culture. Better understanding may lead to better use of resources or a lessening of outright competition for the resources.
Human technology is reaching the point where it might be able to detect such a threat and allow us to do something about it. The danger exist, knowledge can allow us as a species to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.
While Earth is the only planet known to sustain life, surely the adaptive ability of humans would allow other planets and moons to become inhabited. True the life style would be different, but human life and cultures have adapted in the past and surely could in the future. Our genetic makeup will allow humans to move into unoccupied niches and flourish.
The culture group holding the high ground, in this case space, has attained a great advantage over other groups. It can see farther, act sooner and be safer from attack. In space all of these things are true. The culture which expands is like and organism which adapts. It may be found everywhere. If one group is eliminated, the species as a whole survives.


TASK 3

Factors Which May Contribute to Heart disease (also called: Cardiac disease)
in Western Society

If you're like most people, you think that heart disease is a problem for other folks. But heart disease is the number one killer in the U.S. It is also a major cause of disability. There are many different forms of heart disease. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and happens slowly over time. It's the major reason people have heart attacks. Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.
Extensive clinical and statistical studies have identified several factors that increase the risk of coronary heart disease and heart attack. Major risk factors are those that research has shown significantly increase the risk of heart and blood vessel (cardiovascular) disease. Other factors are associated with increased risk of cardiovascular disease, but their significance and prevalence haven't yet been precisely determined. They're called contributing risk factors.
The American Heart Association has identified several risk factors. Some of them can be modified, treated or controlled, and some can not. The more risk factors you have, the greater your chance of developing coronary heart disease. Also, the greater the level of each risk factor, the greater the risk.
What are the major risk factors that can not be changed?
• Increasing age — Over 83 percent of people who die of coronary heart disease are 65 or older. At older ages, women who have heart attacks are more likely than men are to die from them within a few weeks.
• Male sex (gender) — Men have a greater risk of heart attack than women do, and they have attacks earlier in life. Even after menopause, when women's death rate from heart disease increases, it's not as great as men's.
• Heredity (including Race) — Children of parents with heart disease are more likely to develop it themselves. African Americans have more severe high blood pressure than Caucasians and a higher risk of heart disease. Heart disease risk is also higher among Mexican Americans, American Indians, native Hawaiians and some Asian Americans.
What are the major risk factors you can modify, treat or control by changing your lifestyle or taking medicine?
• Tobacco smoke — Smokers' risk of developing coronary heart disease is 2–4 times that of nonsmokers. Cigarette smoking is a powerful independent risk factor for sudden cardiac death in patients with coronary heart disease; smokers have about twice the risk of nonsmokers. Cigarette smoking also acts with other risk factors to greatly increase the risk for coronary heart disease. People who smoke cigars or pipes seem to have a higher risk of death from coronary heart disease (and possibly stroke) but their risk isn't as great as cigarette smokers'.
• High blood cholesterol — As blood cholesterol rises, so does risk of coronary heart disease. When other risk factors (such as high blood pressure and tobacco smoke) are present, this risk increases even more. A person's cholesterol level is also affected by age, sex, heredity and diet.
• High blood pressure — High blood pressure increases the heart's workload, causing the heart to thicken and become stiffer. It also increases your risk of stroke, heart attack, kidney failure and congestive heart failure. When high blood pressure exists with obesity, smoking, high blood cholesterol levels or diabetes, the risk of heart attack or stroke increases several times.
• Physical inactivity — An inactive lifestyle is a risk factor for coronary heart disease. Regular, moderate-to-vigorous physical activity helps prevent heart and blood vessel disease. The more vigorous the activity, the greater your benefits. However, even moderate-intensity activities help if done regularly and long term. Physical activity can help control blood cholesterol, diabetes and obesity, as well as help lower blood pressure in some people.
• Obesity and overweight — People who have excess body fat are more likely to develop heart disease and stroke even if they have no other risk factors. Excess weight increases the heart's work. It also raises blood pressure and blood cholesterol and triglyceride levels, and lowers cholesterol levels. It can also make diabetes more likely to develop.
• Diabetes mellitus — Diabetes seriously increases your risk of developing cardiovascular disease. Even when glucose (blood sugar) levels are under control, diabetes increases the risk of heart disease and stroke, but the risks are even greater if blood sugar is not well controlled.
What other factors contribute to heart disease risk?
• Individual response to stress may be a contributing factor. Some scientists have noted a relationship between coronary heart disease risk and stress in a person's life, their health behaviors and socioeconomic status. These factors may affect established risk factors. For example, people under stress may overeat, start smoking or smoke more than they otherwise would.
• Drinking too much alcohol can raise blood pressure, cause heart failure and lead to stroke. It can contribute to high triglycerides, cancer and other diseases, and produce irregular heartbeats. It contributes to obesity, alcoholism, suicide and accidents.
