There are more bicycles than residents in the Netherlands,and in cities

like Amsterdam and The Hague up to 70% of all journeys are made by bike.

    The BBC's reporter,Anna Holligan,examines what made everyone get back in the saddle（车座）.

    Before World WarⅡ,journeys in the Netherlands were mainly made by bike, but in the 1950s and 1960s,as car ownership increased quickly,this changed.As in many countries in Europe, roads became increasingly crowded.

    The jump in car number caused a huge rise in the number of deaths on the roads.In 1971 more than 3,000 people were killed by motor vehicles,and 450 of them were children.In response a social movement demanding safer cycling conditions for children was formed.Called Stop de Kindermoord,it took its name from the headline of an article written by journalist Vic Langenhoff whose own child had been killed in a road accident.

    The Dutch love of the motor vehicle was also shaken by the Middle East oil crisis of 1973,when oil-producing countries topped export to the US and Western Europe.

    These twin pressures helped to persuade the Dutch government to invest in improving cycling infrastructure（基础设施）and the Dutch urban planners started to change from the road-building policies designed mainly for cars.

    To make cycling safer and more inviting,the Dutch have built a vast network of cycle paths.These are clearly marked,have smooth surfaces,separate signs and lights for those on two wheels,and are wide enough to allow cycling side by side and overtaking.

    Even before they can walk,Dutch children live in a world of cycling.As babies they travel in special seats on bikes.As the children grow up they ride their own bikes.And,as the Dutch are not allowed to drive until 18,cycling offers teenagers an alternative form of freedom.

    The state also plays a part in teaching,with cycling lessons a compulsory（必修的）part in Dutch schools.All schools have places to park bikes and at some schools 90% of pupils cycle to class.

    We all have different ways to navigate (导航) when lost—whether asking a stranger for help, consulting an old-school map or simply following our nose. But on a bike, the risks are higher. One wrong turn or that you're in a traffic jam with two lanes between your bike and the nearest pavement may ruin your good mood. Although cyclists, of course, managed to navigate before smart phones, cyclists can make two choices: a few stay calm and embrace getting lost, and the rest turn to a navigation app.

    Google Maps added a directions function for cyclists in 2015 in the US and Canada, and two years later across Europe. And while there are dozens of other apps now offering a similar service, Google Maps has the demerits for many, so the app seems to be falling behind expectations.

    As someone with no sense of direction, I knew it wouldn't be easy when I started cycling earlier this year. I appreciated that the app gave me two warnings before I needed to turn off a road, and automatically recalculated my route if I accidentally went off course. But still, it wasn't a smooth process. Google Maps thought I could cut across a double carriageway with no breaks in its barrier, assumed I knew what it meant when it told me to “head west”, and thought nothing of taking me the wrong way down a busy one-way street.

    Cyclists don't just want safety—they want convenience. Londoner Robson Smith regularly cycles between Clap ham and the City of London and would like to see Google Maps calculate routes where his bike is allowed on public transport and more choice of the type of routes he can take. “Google tends to calculate the most common and comfortable cycle routes. It would be better to have an option which included the fastest route, regardless of comfort,” he says.

    For this reason, Robson says he uses the app Cycle Streets instead. It offers a choice of four different route modes, based on the type the user wants, and saves previous routes. It also tells you how many calories a route burns, how many traffic lights you wilt encounter, and how busy it is.

    The United States estimates that about one out of every 10 people on the planet today is at least 60 years old. By 2050, it's projected to be one out of 5. This means that not only will there be more old people, but there will be relatively fewer young people to support them.

    Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics. "Population aging increases the concentration of population in the older ages and therefore it is expensive," he said.

    Aging populations consume (消耗) more and produce less. With more people living longer, it could gel expensive. But Mr. Lee says with continuing increases in worker productivity and wise planning, it can be manageable.

    Societies have different methods for caring for the elderly，but each carries a cost Generally, there are three types of support Seniors can live off the wealth they gained when they were younger. They can rely on their family to take care of them, or they can rely on the movement.

    In industrialized nations, governments created publicly-funded (公共资助的) support systems. These worked relatively well until recent years, when aging population growth in places like the United States and Western Europe began to gradually weaken the systems' finances(资金). These nations now face some tough choices. Mr. Lee says the elderly in some of these countries must either receive less money, retire later or increase taxes to make the system continuable.

    Most developing nations haven't built this type of government-funded support, but have instead relied on families to care for their elderly. These nations also generally have a much younger population, which means their situation is not as urgent as more developed nations. But Mr. Lee says that doesn't mean they can pay no attention to the issue. "Third World countries should give very careful thought to this process, to population aging and how it may affect their economies — now, before population aging even becomes a problem," he explained.

    I drove a taxi for extra money east of Toronto thirty years ago. Each time a taxi drove up to the front of the Greenwood Racetrack, a group of local kids would run along the sidewalk angling for position by the passenger door. One lucky kid, or rather, the most aggressive one, would open the passenger door and say "Good luck, Mister!" The man getting out of the cab would vaguely say thanks and throw the kid a quarter. It was a routine everybody knew.

    Throughout the summer, one kid caught my eye. He was bigger than most of all the other kids but pushed away by even the smallest. He never made it but never gave up. One day, his chance arrived. As I was pulling up to the sidewalk, all the kids were pushing for a cab just ahead of mine. The boy saw me and walked toward my taxi. As I positioned the passenger door right beside him, he never paused and opened the passenger door, warmly saying, "Good luck, Mister!"

    But the man neither said thanks nor flipped him a quarter. He pushed him aside so hard that the boy fell on the sidewalk. I knew it hurt him badly. I got out in less than 10 seconds, but the man was gone in the crowd. So I looked for the kid. I decided to give him $20 for the effort. By the time I spotted him he was far up ahead, walking away in the opposite direction through the crowd and his head hanging down. When I got the cab turned around I lost sight of him. I never saw him again. I'd like to find him one day and tell him that if only he had stuck around a little longer I would have given him a whole $20.

    I learned from this kid that when things seem so hopeless that you are ready to give up, it's the time when things are most likely to turn around for you.

    Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

    Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they're in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it's time to repaint, go blue.

    Don't forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

Hearing aids usually bring to mind images of ugly, ineffective devices mainly worn by the elderly. But this ill repute (恶名) is quickly changing, as they've recently taken a turn thanks to two innovators, Dr. Marco Vietor and Paul Crusius, who now lead the fastest-growing hearing aid company in the world-hear. com.

Hear. com's years of research led to the development of two game-changing hearing aids-the Silk and Styletto. These impressive devices pack cutting-edge (尖端的) technology in designs that are practically invisible. They also use a unique way that has been clinically (临床地) proven to deliver better-than-normal hearing so you can clearly understand speech in any environment. With additional features like Bluetooth and rechargeability, today's hearing aids are attracting even younger customers skilled in tech.

But hear. com knows it's not just about tech and design. They've put an enormous effort into the entire experience to make hearing care more accessible and more affordable. "Everyone should be able to hear well to live well," Crusius says. "And it's very individual. Each person's hearing loss is different and requires a personalized approach to find the best solution."

"We hear with our brains, not our ears. And it takes at least 30 days for our brain to adjust and relearn how to hear again with new hearing aids," Dr. Vietor says. "To guarantee your best outcome with hearing aids, we developed the industry's first 30-day program, Hearing Success Program, so customers have that extra level of care and knowledge to succeed."

And it's working. Hear. com has now helped more than 100,000 customers improve their hearing. Their A+ rating with the Better Business Bureau and 5-star rating on the customer review platform, Trustpilot, speaks for itself.

Hear. com's "customer first" approach also helps drive the company's success, encouraging employees to act like owners and put customers first. "We're investing heavily in shaping our company culture," Crusius says. "Individuals who work at hear. com say they are here to do more than a job. They're helping change lives all around the world."
