For families on vacation, a playground provides a welcome break. It can also provide a glimpse into the local culture，from the setup of the park to the ways families interact．Here are the designs that live up to that challenge．

Fruit and Scent Playground, Stockholm

    Is there a picky eater on a steady diet of chicken fingers and cheese? Perhaps a trip to Sweden's Fruit and Scent Playground will change his or her culinary(烹饪的)tune. This playground features a banana slide，an orange seesaw，pear huts，a watermelon jungle gym and a pair of cherry swings，all designed by public artist Johan Ferner Strom. Now, who can say you can't play with your food?

Nishi Rokugo Park, Tokyo

    Located between central Tokyo and the city of Kawasaki, Nishi Rokugo combines recycled rubber tires(橡胶轮胎)with traditional playground equipment. In total, more than 3,000 tires of different sizes are used to create tunnels, bridges, tall sculptures for climbing and, of course, tire swings. There's little shade, so you can visit here in the early morning or late afternoon for the most comfortable weather, and be sure to wear your play clothes.

    Bicentennial Children's Park, Santiago, Chile

    Bicentennial Children's playground in Metropolitan Park was built to celebrate 200 years of Chilean independence and improve the lives of Santiago citizens. Dozens of slides are built into the slope, creating a design completely complementary(互为补充的)of the surrounding landscape. Fountains offer some relief from the sun, and ample seating gives parents a place to relax.

    It was one of those terribly hot days in Baltimore. Needless to say, it was too hot to do anything outside. But it was also scorching in our apartment. This was 1962, and I would not live in a place with an air conditioner for another ten years. So my brother and I decided to leave the apartment to find someplace indoors. He suggested we could see a movie. It was a brilliant plan.

    Movie theaters were one of the few places you could sit all day and—most important —sit in air conditioning. In those days, you could buy one ticket and sit through two movies. Then, the theater would show the same two movies again. If you wanted to, you could sit through them twice. Most people did not do that, but the manager at our theater. Mr. Bellow did not mind if you did.

    That particular day, my brother and I sat through both movies twice, trying to escape the heat. We bought three bags of popcorn and three sodas each. Then, we sat and watched The Music Man followed by The Man Who Shot Liberty Valance. We'd already seen the second movie once before. It had been at the theater since January, because Mr. Bellow loved anything with John Wayne in it.

    We left the theater around 8, just before the evening shows began. But we returned the next day and saw the same two movies again, twice more. And we did it the next day too. Finally, on the fourth day, the heat wave broke.

    Still, to this day I can sing half the songs in The Music Man and recite half of John Wayne and Jimmy Stewart's dialogue from The Man Who Shot Liberty Valance! Those memories are some of the few I have of the heat wave of 1962. They're really memories of the screen, not memories of my life.

    A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

    Avoiding temptation (诱惑）is an effective method for maintaining self-control, which is called the “out of sight, out of mind” principle. One recent study, for instance, found office workers are less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

    The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don't believe that one's willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower—at least to a point.

    Willpower may also be made less vulnerable (脆弱) to being exhausted in the first place. Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

    The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year's Eve is the worst possible approach» Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don't try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you'll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won't require making decisions at all.

    Many questions about the nature of self-control remain to be answered by further research. Yet it seems likely that with clear goals, good self-monitoring and a little practice, you can train your willpower to stay strong in the face of temptation.

    Fire fighting is a serious matter. Knowing what to do during a fire can save people's lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators.

    From the lower floors of buildings, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury.

    The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building.

    Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked(漏)into the room.

    On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing.

An increase in a country's working-age population is a blessing. Lots of workers support relatively few children and retired people. So long as the labor market can absorb an increasing number of job-seekers, output per head will rise. That can boost savings and investment, leading to higher economic growth, more productivity gains and developmental speed-up. Yet for countries that fail to seize this opportunity, the results can be tough. 

Consider Thailand. It is rapidly aging. In 2021, the share of Thais aged 65 or over hit 14%, a figure that is often used to define an aged society Soon Thailand will, like Japan, South Korea and most Western countries, see a decreasing supply of workers and flagging productivity and growth without extraordinary measures. Yet unlike Japan and the rest Thailand is not a developed country. It has got old before it has got rich. 

This is a big barrier to Thailand's future development. To protect its aging citizens, many of whom are poor, Thailand's government will have to spend more on health care and pensions (养老金). This will make it harder to invest in productivity-boosting skills and infrastructure (基础设施). And where Thailand goes, many developing countries will follow.

One conclusion is that countries with a working-age burst need seeking more economic growth out of it. India may never have a better chance than the present. It is widely accepted that privatization and looser foreign-investment rules could raise its growth rate. 

Another conclusion is that developing countries need to start planning for old age earlier. They should reform their pension systems, including by raising retirement ages. They should encourage financial markets, providing options for long-term saving and health insurance. And they should try harder to increase female participation in the labor force. Getting more women into jobs would help deal with the fact that women live longer than men, but tend to have less savings and pensions, leaving them in difficult situations in old age.
