Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.

举一反三
This isn’t particularly surprising, because approximately 500 pounds a year of Kopi Lowak make up the entire world supply. What is surprising is why this particular coffee is so rare. In fact, it’s not the plants that are rare. It’s the civet droppings. That’s right, the civet droppings—the body waste of the palm civet. Coffee beans aren’t Kopi Lowak until they’ve been digested(消化) and come out in the body waste of the palm civet.
Palm civets are tree-dwelling, raccoon-like little animals, native to Southeast Asia and the Indonesian islands. They also have a love for coffee cherries. According to Kopi Lowak suppliers, palm civets eat the fruit whole, but only digest the outer fruit, leaving the beans intact(完好无损). While the beans are not destroyed, they undergo a transformation in the animal’s body. A chemical substance in the digestive system of the palm civet causes some changes to the beans to give them a unique flavor(味道). However, this is not the only explanation why coffee beans retrieved from civet droppings have a special flavor all their own. Another possible reason is that palm civets have an unfailing instinct for picking the coffee cherries at the peak of their ripeness.
Kopi Lowak is reported to have a character in taste unlike any other coffee, complex with caramel undertones and an earthy flavor. Currently, most of the world’s supply of Kopi Lowak is sold in Japan, though a few US markets are also starting to stock up on Kopi Lowak.

Sleep experts have long known that getting a good night’s sleep is important.
It helps kids perform their best during the day. A recent study shows that sleep helps improve problem--- solving skills and creative thinking.
For the study, two groups of volunteers answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep.
While you sleep, your brain is busy doing its “homework”. It sorts out information from your day. Getting enough sleep each night can boost your brainpower. That will help you do your best in school. Experts say that, in return, can lead to better grades.

The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration—a lack(缺少) of water in the body. Most people are dehydrated at least some of time, although they probably don’t know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water.
There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

Colds, which usually last about a week, affect the nose most. They commonly cause a runny nose and sneezing. Sometimes, they cause a headache, a cough and slightly aching muscles.
Flu is much more serious illness and is caused by different group of viruses. People with flu usually get all the symptoms described above. However, they also get a high fever, a dry cough and much worse aching. Fever is one of the typical symptoms of the flu for all ages. The symptoms also last much longer. Sometimes they don’t disappear for at least two weeks.
Flu can be a deadly disease. The elderly, who are weaker and less healthy than most younger people, can die from flu. This is one reason why old people are advised to have a flu injection before the start of winter when flu is most common. This injection is inexpensive and definitely worth it.
If you have a cold or flu, you must always deal with used tissues carefully. Don’t leave dirty tissues on your desk or on the floor. Someone else has to pick these up and viruses could be passed on. And finally, remember to cover your nose and mouth when you sneeze!You don’t want to see the small drop of liquids blown out of your nose and mouth when you sneeze, do you? Disgusting, eh? Now you can understand why it’s a good idea to cover your nose and mouth when you sneeze!
