       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 and non­joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate 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 non­joggers. 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, jogging a few times a week at a moderate pace is a good strategy. Anything more is not just unnecessary, and it may be harmful.”

        The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than“iron man” events, triathlons and long­distance 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.”

Earthquake Safety Procedures

An earthquake is a naturaldisaster which occurs when the surface of the earth experiences some kind ofshaking.This happens when the plates of the Earth move together, putting somuch pressure on it that it causes the breakage of the earth's crust.{#blank#}1{#/blank#}Whatever be the reason of theearthquake, it not only has the ability to destruct and damage buildings,houses，electric poles,trees, etc., but also to take the lives of living beings.Therefore, it isimportant for people to know about earthquake safety procedures.{#blank#}2{#/blank#}

One of the main reasons due towhich people lose their life during an earthquake is because they getpanicky.Though it is very difficult to remain calm when the earth under you isshaking，it is very importantto be so.{#blank#}3{#/blank#}If you are inside yourhouse or office when the earthquake begins, do not try to run out of thebuilding.This is because it has been reported that most of the deaths arecaused when people try to move outside the building.When you start experiencingthe vibration, the first thing that you should do is to get under a strong bedor table.{#blank#}4{#/blank#}You can use pillow,newspapers, blanket, big boxes, etc., to protect yourself from fallingremains.Another thing that you have to remember is that you should stay awayfrom china cabinets, tall shelves, mirrors, huge furniture, glass windows,sliding doors, etc., during an earthquake.This is because the shaking andvibration can cause them to fall.{#blank#}5{#/blank#}However,even if you do so, never use the elevator during an earthquake because theelectricity may go off, leaving you stuck in there.
