With the improvement of people’s living standards, people are paying more attention to health problems. Some experts gave us some advice.

Blood donation(献血), also called blood banking, is a wonderful thing to do. It is an easy and direct way to contribute to social work and help the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.

You are able to give or donate blood every three or four month, and it is a great way to make a huge difference to someone’s life and you can always be proud of it after making valuable contributions to society. Blood donation is not a big problem, but you need to keep a few points in mind.

Before donating blood, make sure that the ferrum (铁) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.

For required hemoglobin (血红蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.

For a good blood flow（流动） in your body, drink at least 6-7 glasses of water every day. Completely avoid a day before and after giving blood, taking alcohol (酒). Do not smoke half an hour before giving blood.

When you are going for blood donation, be relaxed, which helps keep the right blood pressure（血压）. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.

When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.

Take a rest for 15 minutes after the donation. It helps you to feel relaxed.

Eat something and drink juice before leaving the blood donation center. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.

Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

For many years, I was sure that my suffering was because of my size. I believed that when the weight disappeared, it would take old wounds, hurts, and rejections with it.

Many obese（overweight）people also mistakenly believe that changing our bodies will fix everything. Perhaps our worst mistake is believing that being thin means being loved, being special, and being cherished. We imagine what it will be like when we reach the long-awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there.

But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally realize its promise of happiness, and of course, love.

It took me a long while to know that there was something more for me to learn about beauty. Beauty standards are different with culture. In Somoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us try hard to change our body, but with no result. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves,  the whole world changes.
