2 . About 1.4 billion people around the world do not get enough physical exercise. The world's adult population is about 5.6 billion, so that is tantamount to about one-fourth of the world's adult population.
Researchers looked at 358 population-based studies between 2001 and 2016. Those studies referred to nearly 2 million people in 168 countries.
Regina Guthold was the lead author of the report. She said the study also found a wide range (范围) of physical activity levels for countries around the world. “Inactivity ranges from as low as 6 percent in Uganda and Mozambique to 67 percent in Kuwait. Four countries have a prevalence (普通) of inactivity of over 50 percent. That's Kuwait, America Samoa, Saudi Arabia and Iraq,” she said.
The report shows the levels of physical inactivity are more than two times as high in wealthy countries as they are in countries where people have low incomes. In wealthier countries, people are more likely to spend time sitting in offices. They are also more likely to use computers and electronic devices (设备) for entertainment.
There are actually many things people can do for themselves. If you work in a high-rise office building, take the stairs instead of an elevator. Go for a walk during your lunch break. Take more breaks during the workday and move around. If your workplace offers a gym or exercise classes, make sure to use them. At home, take walks with your family or friends after dinner.

3 . 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 (慢跑者) 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 effects.
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”.
