The rising costs of health care have become a problem for many countries in the world. To deal with this problem, it is recommended that a big part of the government’s health budget（预算)be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.

Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. For example, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.

One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.

In addition, health education plays a key role in improving people’s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one’s family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.

However, stressing disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.

It's not easy feeling like you're always under the spotlight being judged for each little mistake you make. Your mind is in an endless circle playing what you said and did over and over again. You wish you had a time capsule to go back and make things fight if you find mistakes. You fear what others will think about you and that they will reject and dislike you. You seek to be socially perfect.

Academically，you work long endless hours just to make those excellent marks. Although most would say "it's good to have high standards，"they have no idea about the internal hell you put yourself through to achieve perfection. If you come up less than your desired goal you feel as though you have failed, but you're far from failing, you just don't see it that way. So instead you are telling yourself that you're stupid, and not smart. The pressure you place on yourself weighs you down and you wear the "not good enough" label each and every day.

You not only have high standards for yourself but you also have them for others. If people don't perform up to your expectations, then you think them incompetent. This causes a lot of frustration because you can't trust anyone to get things right. So instead of being a team player you fly solo(单飞)and try to do two or three jobs at once. Your unrealistic expectations cause you to criticize and judge others and that leads to problems in other areas of your life.

The attempt to be perfect is called perfectionism and it's the unachievable American dream that's damaging our emotional and mental health. We strive for perfection with our body, in our performance，and in our relationships. In a society that overstates mistakes, is it any wonder that so many young people attempt the impossible task of being perfect？

We all have flaws, fears, and make mistakes, and that's perfectly OK. It's our imperfections that make life interesting and they help us grow into a stronger more adaptable person. We don't have to strive to achieve the impossible. We are designed to be perfectly imperfect.
