【推荐3】April is the cruel-lest month... Or so said gloomy poet T S Eliot in his long poem, The Wasteland. It seems he wasn’t wrong. SAD(Seasonal Affective Disorder)—otherwise known as the “winter blues”—is a well known condition. But, surprisingly, some people feel more depressed in spring and summer than at other times of the year. The days getting warmer and longer, and the fact that spring flowers and blossom represent new beginnings for some people, just make the spring blues worse for others.
What Causes Reverse Sad?
Because it’s not well understood or often spotted, it’s hard to pin down the reasons for feeling down when everyone else seems to be full of the joys of springtime. With winter SAD, less sunlight is thought to disrupt the body’s internal clock and bring on depression.
How Do You Recognize It?
Exercise can work wonders. A study found that ten weeks of standard exercise was 20 per cent more effective than medication. And get plenty of sleep. Try to get up at the same time every day, even if you haven’t slept well.

【推荐1】The ideal body is often presented as one with a stomach having no fat, or better yet, defined (棱角分明的) muscles.
Many have tried to reach that goal by exercising. Some change their diet or simply eat less. Now doctors at the University of Miami have created a new plastic surgery (塑身手术) process called abdominal etching, which could replace all that hard work.
The study followed 26 men and 24 women averagely aged 36, who already had a healthy diet and got some exercise, but all had unwanted stomach fat.
During the surgery, doctors removed fat from different parts of a body. Then they moved the fat around and etched (蚀刻) lines in the stomach to make them appear to be the outline of muscles. After the surgery, the patients appeared to have a muscular (肌肉发达的) stomach of a person who spends hours exercising every day.
Stomach fat is the hardest fat to lose on the body. It is deeper inside the body than leg or hip (臀部) fat, and it often increases with age. Recently, several non-surgical, fat-reducing processes called “body sculpting” have become popular in the United States. They include freezing fat or hitting it with radio waves. Both processes supposedly kill fat cells in the body. But they cannot get to that deep stomach fat that abdominal etching removes.
After the surgery, patients had to follow a lot of rules. They had to cover their surgery scars with pieces of tight foam (泡沫) for several weeks to keep the lines in place. They also needed to visit doctors regularly to check for problems. One month after the surgery, they still have to exercise every day and keep to a diet for up to six years.

【推荐2】Many people experience problems with their spine(脊椎) as they age. The tissue that protects the joints in the spine gradually breaks down. As a consequence, the bones, in the spine begin to rub against each other. This further harms that issue as well as the bones. The result is pain in the joints and, sometimes, in nerves near the spine
This painful problem is actually a disease called osteoporosis. Some people are more at risk of osteoporosis because of genes that they inherited from their ancestors. Extremely heavy people are also more likely to suffer from this disease because their extra weight puts much pressure on their joints. Fortunately, there are steps that people can take to help prevent osteoporosis from developing in their spine.
The most important step is exercise. Stretches can help the muscles around the spine relax and allow bones to shift into better alignment(排列), Strength exercises with light weights or bodyweight exercises like pushups can also help by strengthening the muscles around the spine. However, people should not overdo these exercises as repeated motions can strain the muscles around the spine. Trying to lift heavy weights with poor technique can have the same effect.
Another important factor is diet. It affects the health of spine because many vitamins are necessary for bones and nerves. These include B vitamins and omega-3 fatty acids, all of which helps keep nerves healthy. People can get more B vitamin and omega 3 fatty acids by taking supplements sold by stores. Another important factor is vitamin D. which is essential for strong bones. All of these vitamins and acids can be obtained from food. Thus people can help themselves by including them in their daily diets
