Jumping off random cliffs(悬崖) into the sea is not clever. However, as a sport, coasteering uses local experts to help groups travel around the coast so they can then jump safely and have a lot of fun in the process. But coasteering is also so much more than cliff jumping.

    A usual day's coasteering will involve swimming, climbing, scrambling(攀岩) and cliff jumping. All trips begin with a safety brief and equipment check. You will be equipped with a helmet, wetsuit and life vest. You will need to wear some old sneakers you don't mind getting wet.

    From here it could be a short swim to the first jump site. Following an instructor, you swim through rock pools, around rough rocks and right up to the next jump spot. A brief climb and you'll be standing on the edge wondering, “Why the hell did I agree to this?” Then, and to the yell of your friends, you're leaping in, with a smile that's guaranteed to last the rest of the day.

    Coasteering is certainly more than cliff jumping. If ever a sport could claim to be confidence building, this is it. And it's also a perfect activity for groups of friends or for adventurous families who want to explore the coast. Many companies offer daily trips, so even if you are on your own or a couple you can join in with a large group. Companies use trained guides with much knowledge of local tides and weather conditions. These people lead the show and are qualified lifesavers as well.

    Coasteering is already popular around the UK. At least now you won't have to ask “What is coasteering?” if someone you know gives it a go.

Seal(海豹) seizes raft

    This seal really rocked the boat when he found himself an unusual place to hang out. After the seal came across a boat in the harbor where he lives, he fell inside and wouldn't budge for four days.

“One morning the seal just pulled himself aboard,” says Ed Stubbings, who owns the boat-turned-bed. Probably thinking the boat was a rock, the seal made himself at home. The seal didn't move an inch—--not even to eat or drink.

    Stubbings was a little worried that the 500-pound animal might sink it. Luckily on the fifth day, the seal fell back into the water and swam off.

Alligator(短吻鳄)gets new tail

When Mr. Stubbs the alligator swims through his pool at the Phoenix Herpetological Society, he looks like any other gator—--except that his tail is made of rubber. Mr. Stubbs is the first alligator known to wear an artificial tail.

    Mr. Stubbs was brought to the society nine years ago. “His tail was missing when he arrived,” says President Russ Johnson. Mr. Stubbs couldn't walk or swim properly. “We showed him how to swim in the water,” Johnson says. “But that hurt his back.” Later, the scientists used rubber to build an artificial tail attached to Mr. Stubbs's back legs. “Once we put the tail on him, he walked with ease,” Johnson says.

Dog delivers papers

    Morgan started her “paper route” when she was young. One day as Morgan and her owner Bill set out on a walk, she spotted a rolled-up paper. To Bill's surprise, Morgan grabbed the object in her mouth, walked back to the house, and dropped it on the doorstep. Morgan enjoyed the activity so much that she wanted to deliver every paper she saw on her walks.

Now three-year-old Morgan brings the paper to her owner and neighbors, even in bad weather. “Morgan has a natural instinct(本能) to carry things with her mouth,” dog behaviorist Pat Miller says. “And she feels rewarded by the activity, so she keeps it up.”

    People with an impulsive(冲动的)personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren't necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight. Food addiction has been compared to addictive drug use. Studies have linked the dopamine (多巴胺)release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.

    Impulsive behavior involves several personality traits(特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI(身体质量指数)during the study. Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity(肥胖). “Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight,” said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. “We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action,” said Gearhardt.

    Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies used to treat addictive drug behavior could help people who suffer from addictive eating habits.

    “Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise,” MacKillop said. “It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily.”

    Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange, but a study suggests this might be true.

    Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, color had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament. Again, teams wearing red won more games.

    The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male show red on its body, it sends a signal of its power and strength. For example, in many kinds of monkey, the more the male shows off its red scare, the more females it can attract

    Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that his competitor could be stronger than him. And that kind of feeling may have a bad influence on the player's performance in the actual game.

    Although the idea is Interesting, most people don't accept that color signals in the animals world can really be useful to humans in sports. They think that it is unreasonable to develop an Idea based on such a small number of examples. Much more research has to be done to prove the influence of uniform colors on the performance of athletes.

    Hey, ladies! It's summer again and it's time for a new you! No more make-up, no more pretending! Yes, that's right! It's time to stop making ourselves beautiful for the camera, and start posting confident pictures without all the make-up and extra tricks we add onto ourselves in the hope of appearing more attractive and beautiful. Because believe it or not, we already are!

    After we wash our face and go to bed, it is not so perfect. You know it the face we should confidently be showing to the world! Who cares if you have pimples（面痕）or your eyes look small, or if you have crow's feet? Guess what? Those are actually what make you such a beautifully grown woman. And any person who doesn't think so is just not as strong as you.

    Nowadays we are so prone to do anything and everything to make us look as young and perfect as possible. Yet the truth is, by doing this, we are actually making our tree skin get worse and badly affected by all the junk we put on. We are making ourselves believe that by changing our appearance we will be more accepted and seem more attractive to other people. And yet, our final goal is to find that without all of the make-up. What kind of twisted（扭曲的）game are we really playing with ourselves?

    So I would like to make a suggestion for all women out there to give yourself a break at least this summer. Take a couple of pictures without all of that make-up on. You don't need it every single day, especially not this hot summer! You'll be surprised that the more confident you are about showing the real side of you, the more attractive you will be to everyone else.

    Yes, the saying, “Beauty comes from within” is an old one, definitely still holds some troth today. So be brave, carefree, and make-up free! Let the world see you for who you really are!

    Surgery that can improve the way a person looks is being more and more popular in the United Stated. This kind of surgery is called cosmetic surgery, and both men and women are turning to this treatment as a way of keeping their appearance young as well as keeping competitive in their jobs. Men especially are beginning to turn to face-lifts, liposuction, and implants to help them look younger. As companies downsize and move younger employees into higher positions, older employees in their late forties and early fifties feel the need to look and act younger in order to stay competitive. A younger look through cosmetic surgery may give an older employee a few more years on the job.

    These operations are not without dangers, however. One young woman had an eye operation to get rid of the bags under her eyes. She described her experience as terrible. She said, "When he started cutting, I was fully awake. Even though he'd given me an injection(注射) near my eyes, I saw everything. "She went on to explain, "I knew I had to keep still because of what he was doing. He was removing fat under my eyes. It took about ten minutes. After he finished I felt I couldn't walk. I was so weak." Her troubles did not end after the operation. For two weeks, her eyes were swollen and almost completely closed, and even dark glasses could not hide the side effects of the operation.

    Liposuction is probably the most popular cosmetic operation in the United States. It seems simple enough. First, a small cut is made over the places where the patient wants the fat removed. Next, a small pipe is put into the cut. A machine is then turned on, and the fat is taken right out of the body. However, as one doctor explained, some problems can happen after the operation. He warned, "Irregular lumps(块) and loose skin can result from this operation. If it is not completely done, liposuction can produce a very lumpy result." Patients often must have more liposuctions to correct the problem.
