1 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular (心血管的)fitness in middle age could delay or even prevent them from developing dementia. "
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak (最大值的) cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

3 . The Biggest Stadiums in the World
People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.
These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.
For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.
All these stadiums are still functional, still open and still hosting the biggest events in world sport.

6 . When you go for a run outside, chances are that you’ll find litter all around you. Do you just go past it, or do you stop and pick it up? If you choose the latter, you’re part of the latest fitness trend that’s sweeping the West: plogging.
The word “plogging” combines the Swedish phrase “plocka upp” (pick up) with the English word “jogging”.
Running – especially marathons – is often associated with good causes. And plogging, which combines environmentalism with fitness, has become the new poster boy for the environmentally-friendly runner. All a plogger needs is a trash bag, and ideally a pair of gloves to protect their hands.
The process of collecting garbage is simple, but it sheds light on serious environmental issues. “When I usually walk through the streets of New York, the sight of newspapers, lost hats, and shattered glass doesn’t bother me,” Matthew Sedacca of Men’s Health magazine wrote. “But when I was plogging and focused on trash collecting, the amount of garbage strewn (散布) across the sidewalks and along the pavement was kind of shocking.”
While collecting garbage, ploggers learn to classify and dispose of it correctly too. Laura Lindberg, a plogger who lives in New Jersey, US, always keeps a note of what she’s collected in her mind. This way, she knows what can stay in her trash bag and what can go in a nearby recycling bin.
It may be difficult to measure the sense of self-satisfaction that comes from making the world a cleaner, greener and more beautiful place, but the health benefits of plogging are easy to see. According to the Swedish fitness app Lifesum, a 30-minute plogging burns around 288 calories, compared to 235 calories burned from just jogging.
So the next time you go out jogging, why not carry a trash bag and collect some litter along the way? Your body and the environment will thank you.
