    University graduates Mallorie Brodie and Lauren Hasegawa, who invented a smartphone app that tracks construction defects for commercial builders, had a tiger by the tail.

    Bridgit, which they founded in 2012, launched a cloud-based communications platform that helped manage defects on construction sites, which can delay projects and result in costly repairs if left unchecked. The smartphone application lets site supervisors take photos of cracks or damaged paint, share them with employees and track the problems to solution.

    More than 600 subcontractors used the pilot version in many building sites before the commercial version, called Closeout, officially launched.

    Feedback(反馈)was so good that they began to wonder: Why limit their invention to a specific industry? Why not turn it into some kind of a handy tool for consumers too? This became their dilemma. In other words, should they stay the course or look for wider applications of their app?

    The experts polled all agreed Bridgit should stay focused on its original goal. Ms. Hasegawa and Ms. Brodie took that advice.

    As more business customers signed on, it became clear that they made the right decision. Since then, the company's growth has been rapid.

    Earlier this year, Bridgit launched Closeout ,which is designed so that even the least tech-savvy can use it easily. Today, the app is being used on sites across Canada and the United States and even by top general contractors.

    In October, Bridgit was named to the Canadian Innovation Exchange's top 20 list of Canada's most innovative (创新的) companies working in digital media and information and communication technology .

    But Ms. Hasegawa and Ms. Brodie are not resting on their glories. They have also been collecting feedback on Closeout from customers, and they'll launch a new version in the spring. It will target not only general contractors but developers and building owners, too.

    Mexico sites on an island plateau (高原) surrounded by volcanic peaks, which makes air quality a constant concern for people who live there.

    In April, the country took a decisive step toward improving air quality by enacting a temporary ban on private and Federal vehicles in the city. The rule forbids people from driving in the city one day each week and one Saturday each month. Electric vehicles, government service vehicles, public transport options and school buses are not included in the ban.

    Mexico City isn't the first urban center to be involved in car-free living. But the ban is more than an awareness-raiser. It was enacted with the direct aim of solving air pollution. In March, the city sank into a deep brown haze of smog when the pollution levels passed the 200 mark. The city ordered some 1.1m of the area's 4.7m cars off the streets and also offered free bus and subway rides.

    Mexico City's temporary vehicle ban raises questions about the best ways to improve urban air quality. India, whose citizens breathe some of the world's dirtiest air, has tried a variety of solutions. Earlier this year, the Indian government started a 4% sales tax on new-car purchases.

    Beijing also has experience with cleaning the air. The city introduced alternate-day rules in advance of the 2008 Olympic Games, which produced good results. And then there is the London congestion (拥挤) charge, introduced in 2003. The charge has had a measurable effect on air quality.

For now, Mexico City — named by the United Nations as the most polluted city on the planet in 1992 — can look forward to the start of the region's rainy season, when daily showers will help lo clean the air.

Be careful on January 8^th — It's officially the most dangerous day of the year. The insurance company Hyperion has studied accident statistics(统计数字) and has found that there are more accidents on January 8^th than on any other day.

    Accidents are certainly more likely to happen at particular times of the year. One general rule is that more accidents happen in winter months, because risk increases in bad weather. In 2004 and 2005 Hyperion found that the worst day was January 8^th, with 298 accidents reported to them. March 3^rd was the safest day, with only 89 reports. Six of the ten worst days for driving were in January.

    It's clear that icy and snowy conditions are dangerous, but some other statistics are puzzling. A British Medical Journal report in 2001, for example, found that hospital admissions(住院) were always higher than usual on Friday the 13^th.

But it is not only when Friday falls on the 13^th that it is a dangerous day. Four of the top ten worst days for accidents last year were Fridays — perhaps because everyone is rushing home for the weekend — while Thursdays are the safest day of the week.

At what time of the day is an accident most likely to happen? The Health and Safety Authority found that people are most likely to have an accident at 11.00 a.m., while the safest time of day is between 4.00 and 5.00 a.m. — probably because most people are in bed!

    Finally, good news for Harry Potter fans. Doctors at the John Radcliffe Hospital in Oxford noted that fewer children were in hospital on the weekend when Harry Potter books were available to the public. Casualties(伤亡人员) fell by over 50% when the last two books went on sale. So if you want to be really safe, you should read a Harry Potter book in bed, at around 5.00 on a Thursday morning, in summer.

    I came to the United States ten years ago. I would always say that I was trying to study, but there were always things like work and my kids that would not allow me to start.

    Now I realized that those were only excuses. What stopped me was that I was afraid to start studying again. I always believed I would learn by myself.

    One day, however, my son told me that he was sad because his friends would come over and I didn't understand them because I didn't speak English. He was also sad because I could never help him with his homework. That same day, I told myself, "Rocio, you have to start believing in yourself and you will see you can make it."

    The next day, I went downtown to look for a big banner (横幅) in front of the school which said that they offered classes for adults. I came in to see if I could join, but the classes were closed already. That night I took the kids to the movies, and on the way back, I told them we would take a new route. I ended up getting lost. That's the way I found Chaffey College. The following Monday, I went to ask for information. They told me that summer school was starting that week.

    That's how I started studying English last summer. It is difficult, but I have had great rewards. My daughter had written a story for school. It was about the female they most admired and why. She wrote that I was the person she most admired because I had started going to college. I will never forget this.

Bill Sumiel was having a tough Friday. It was October 2020, and the 71-year-old, who was dealing with kidney(肾)failure and had been on dialysis( 透 析 )for a few years, found himself away from home. 

He'd been diagnosed with diabetes(糖尿病) over 20 years before, which led to his kidney problems. He was on the transplant list, but no matches had yet appeared. So he continued with his treatments periodically. Without a ride lined up for Friday's do-over, Sumiel took Ubers to and from his appointment. 

Timothy Letts, 31, was driving to visit a friend when his phone received the request for Sumiel's ride home. When Sumiel got into his car, Letts could see that the older man was unenergetic but in good spirits. And as they set out to Sumiel's home, the pair got to chatting. During conversation, Sumiel revealed that he was searching for a kidney donor. Letts joked that he'd be a good donor candidate, given that he didn't drink or smoke. 

Sumiel agreed, though he didn't think much of it. Letts, however, couldn't stop thinking about it and it was always on his mind. So, Letts said:"I'd like to see if I could be a match to give you a kidney. "

"I was shocked, "Sumiel recalls. He was shaking so hard that he could barely write his name when they exchanged contact information. After the initial excitement, Sumiel started feeling less optimistic. He was touched by Letts's offer, but he wondered if it had just been an emotional moment. Would he hear from him? And what was the likelihood of a match?

But Letts was true to his word. He got in touch with Sumiel just a few hours later, and by the next week, Letts had contacted the kidney transplant program. After a series of testing, the results were in: Letts was an ideal donor, and he and Sumiel were a perfect match. 

In December 2021, 14 months after their chance encounter, Sumiel and Letts had their surgeries. It was a success. Today they live respectively and healthily and anticipate the day they can reunite.
