Hello, everyone! My name is Li Hua. 

That's all. Thanks for listening!

I had been working for a company in Australia for more than ten years. I had just found a better job and I knew that the manager would be disappointed when I was leaving. I recently became friends with a young man who had just migrated to Australia to escape war in his homeland. He was unskilled and was finding life difficult as he was unemployed. 

The manager asked me to introduce someone who I thought could do the job just as well as me, so I took this opportunity to arrange an interview for my new friend. However, in the end, he was not offered the job after the interview. 

Later, I asked the manager why my friend was turned down. The manager thought that his English was not good enough for the position, but I suggested that my friend will be a good choice for the company since I could train him. I believed that once given the time to learn, he could do the job. After a week's training, he was employed and was happy with his position.

I knew how the terrible war had forced him to leave his homeland and what price he had paid for doing so. I appreciate being able to live in Australia and believe that this appreciation is best proved by offering acts of kindness to people in need of help. The smile of appreciation from this man continues to impel me to give, which is a very happy and enjoyable process, during which I also receive some unexpected things, such as help, prize, flowers, love and so on. 

Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises according to scientists. They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories to produce heat. 

Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks even if they ate more. US researchers say that social excitement catalyzes weight loss by turning white fat into brown. White fat stores calories and makes us fatter while brown burns energy to produce heat. Turning white fat into brown is extremely difficult normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.

However scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown. The team came up with their theory by studying the effects of various living environments on mice. Those who lived alongside a greater number of mice had more space and toys to excite themselves and then lost far more weight over the course of the study than their "couch potato" fellows.

Study author Dr Matthew During whose team's findings appear in the journal Cell Metabolism said "I'm still amazed at the degree of fat loss that occurs. " Explaining how new technology had threatened face-to-face socializing he added "It's not just a sedentary (久坐的) lifestyle and high calorie foods but an increasing lack of social activities. " Co-author Dr Lei Cao said, "Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent. Social activities are very vital. "
