When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood-stream. If the danger continues, this animal will do one of the two things. It will defend itself, or it will run away as fast as it can. Something like this also happens to people. When we are excited, angry, scared, or aroused by other emotions, our bodies go through many physical changes. Our hearts beat faster, and our muscles get tense. All of these changes make us more alert and ready to react. We, too, get ready to defend ourselves or run. Human beings, however, have a problem. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger - and regretted later? Have you ever shouted at a teacher or told somebody you were lonely and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely. Does this mean that it's always smarter to hide our feelings? No! If you keep feelings like anger hidden away or bottled up inside, your body stays tense. Physical illnesses can develop, and you can feel disturbed badly inside. _ can actually be bad for your health. Feelings that you keep all bottled up inside don't just go away.

And if you opened the cupboard, chances are you'd see little fruit flies hovering all over them. They'd be rotten. You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don't exit, but they'll still be around. And at last you'll have to deal with them, just like those bananas.

This is the latest in a string of food and drug safety scandals in a country where parents often import products for infants and babies from overseas to ensure quality. Many remember with fear the 2008 milk powder scandal, in which infant formula laced with melamine caused at least six deaths and 300,000 children to fall ill. Beijing last month made public an illegal operation in eastern Shandong province in which a hospital pharmacist and her daughter traded $88m in vaccines that may have been compromised because they were expired or improperly stored or transported. The China Food and Drug Administration said, however, that the vaccines posed no greater than the normal risk to patients. "We don't see that the vaccines' effectiveness has been reduced," added the health watchdog in a report. Nonetheless, health officials fear a backlash against Chinese-manufactured vaccines, which already have a reputation for being more dangerous than those made overseas. Wang Yuedan, deputy director of Peking University's immunology department, said the key to evaluating risks is to check whether package seals are broken or for pollution with micro-organisms. "The vaccines in the Shandong case don't have those problems," he said. Those vaccines had been subject to higher than normal temperatures that could have lowered their effectiveness and reduced their protective value.
