If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers (幔跑者)and non - joggers for 12 years. The death rates from the sample group indicate that people who jog at a proper pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non - joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy(寿命)，jogging a few times a week at a proper pace is a good strategy. Anything more is not just unnecessary, and it may be harmful. “
The implications (暗示 ) of this are that moderate forms of exercise such as tai chi, yoga and walking may be better for us than “iron man events, triathlons and long - distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn’t actually do too much”.

Riding on the road? Time to review all that you learned in elementary school —especially if you'll be riding in traffic.
Always ride on the right side of the street in the same direction as the traffic. Never ride against traffic. Try to use bike lanes (车道)whenever you can.
Always stop and check for traffic in both directions when leaving your driveway. Some people in cars just don't see cyclists.
Watch traffic closely for turning cars or cars pulling out of driveways.
Don' t ride too closely to parked cars — doors can open suddenly!
Stop at all stop signs and stop at red lights just as cars do. Take special care at crossroads. It's d good idea to walk your bike across busy crossroads using the crosswalk.
Don't wear headphones while biking—you need to hear what's going on around you.
Never change directions or change lanes without first looking behind you and using the correct hand signals. That way everyone knows where you' re going. You can use your left arm for all hand signals. To show you' re making a left turn, hold your arm straight out to the left. To show a right turn, bend your elbow(肘部)，holding your arm up in an “L” shape. And before you stop, bend your elbow, pointing your arm downward in an upside down “L” shape. Of course, you can also hold your right arm straight out to the right to show you are going to turn right.
Biking is a fun way to get exercise and a great way to get around, but bike injuries are common. So follow these tips to really enjoy your ride.

Sonya took Rupert, a rescue dog, back home three years ago, and soon found it liked attacking strangers and other animals, which she believed was caused by pain.
It took Sonya a year to develop a normal relationship with Rupert, during which she learned it was afraid of being left alone and also couldn't walk properly. Finally, she decided to take it to see a vet (兽医). After examining Rupert, the vet said its leg was broken, and it needed an immediate operation.
But when it had to go in for an operation on its leg, there was a problem - the vet Mike couldn't get near the dog. Mike and Sonya were left scratching (抓)their heads until one of them came up with an idea. Sonya said Rupert slept on a mouse suit so she suggested that Mike put it on.
At first, the dog barked (吠叫) wildly when Mike tried to operate on it in usual clothes. To make his patient feel at ease, Mike decided to dress up in the mouse clothes to see if it would be less worried. Amazingly, it worked. It stopped barking and immediately became good friends with Mike when he put on the suit. As a result, he was able to perform an operation on the leg safely and the result was quite satisfying.
After the successful operation, Mike hugged the dog around the neck, which isn't usually well - received by pets. Mike tried to be as respectful of its needs as possible and made time to give some attention. What Mike had done created a special experience or event in the dog's life.
