Mom was a teacher most of her life. When she wasn't in the classroom, she was educating her children or grandchildren: correcting our grammar; starting us on collections of butterflies, flowers or rocks; or inspiring a discussion on her most recent “Book of the Month Club” topic. Mom made learning fun.

    It was sad for my three brothers and me to see her illness in her later years. At eighty-five, she suffered a stroke(中风) and she went steadily(不断地) downhill after that.

    Two days before she died, my brothers and I met at her nursing home and took her for a short ride in a wheelchair. While we waited for the staff to lift her limp body back into bed, Mom fell asleep. Not wanting to wake her, we moved to the far end of the room and spoke softly. Several minutes our conversation was interrupted by a muffled sound coming from across the room. We stopped talking and looked at Mom. Her eyes were closed, but she was clearly trying to communicate with us. We went to her side.

    “Whirr,” she said weakly.

    “Where?” I asked. “Mom, is there something you want?” “Whirr,” she repeated a bit stronger. My brothers and I looked at each other and shook our heads sadly.

    Mom opened her eyes, sighed, and with all the energy she could gather said, “Not was, say were!”

    It suddenly occurred to us that Mom was correcting brother Jim's last sentence. “If it was up to me…”

    Jim leaned down and kissed her cheek. “Thanks, Mom,” he whispered. We smiled at each other and once again shook our heads…this time in awe (敬畏) of a remarkable teacher.

    The Intelligent Transport team at Newcastle University have turned an electric car into a mobile laboratory named "DriveLAB" in order to understand the challenges faced by older drivers and to discover where the key stress points are.

    Research shows that giving up driving is one of the key reasons for a fall in health and well-being among older people, leading to them becoming more isolated (隔绝) and inactive.

    Led by Professor Phil Blythe, the Newcastle team are developing in-vehicle technologies for older drivers which they hope could help them to continue driving into later life.

    These include custom-made navigation (导航) tools, night vision systems and intelligent speed adaptations. Phil Blythe explains: "For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.

    "But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to."

    Dr Amy Guo, the leading researcher on the older driver study, explains:" The DriveLAB is helping us to understand what the key stress points and difficulties are for older drivers and how we might use technology to address these problems.

    "For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.

    "We hope that our work will help with technological solutions (解决方案) to ensure that older drivers stay safer behind the wheel."

    If you're encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington.

    Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior (外部) of the house was part of a continuous living exhibit in 2015and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

    McMahon said the D.C. government's approval to push companies to hire District residents (居民) was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005 and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

    "When students make the connection between what they are learning and a potential career, their academics improve dramatically," said Carol Randolph, chief operating officer of the D.C. Students Construction Trades Foundation. "Some of them who didn't think college was an choice now have a better chance because their classes have become relevant to a job."

    "We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly," he said. "We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts."

    "Parents and school advisors can be the biggest obstacles because of the negative idea of construction as a blue-collar career," Karriem said. "I get middle-school advisors on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes."

If a president, a philosopher, and one of the best-selling writers credited the same secret for their success, would you try to follow it too? What if the secret was something you already knew how to do? In fact, you probably do it every day. Here's what Friedrich Nietzsche wrote: "It is only ideas gained from walking that have any worth. " Thomas Jefferson: "Walking is the best possible exercise. " Charles Dickens: "If I could not walk far and fast, I think I should just explode and die. "

Researchers have found quite a lot of connections between walking and producing ideas. A Stanford University study found that participants were 81 percent more creative when walking as opposed to sitting. According to the study, walking outside-compared with on a treadmill (跑步机)-produces the most novel and highest-quality ideas.

The movement aspect of walking is obviously key. Our creative thinking is triggered (触发)by physical movement, which is exactly why walking-with your dog, a friend, or alone-feeds creative thinking.

The scenery is almost as important as the sweat. Breaking your routine with a walk can be a catalyst for fresh understanding of problems or projects. Just by going outside, you are stepping out of your familiar surroundings and your comfort zone, which is necessary if you want to open your mind to new possibilities. You can walk through a tree-filled neighborhood. You can walk through a park and observe people joking or birds singing. Being inside, you're more likely to be lifeless, which means you don't have enough energy to wonder or create.

So instead of setting a fitness goal, why not set a creativity goal that starts with walking? Involve yourself more closely in your surroundings. Tum off your phone and give yourself the chance to be present in the world, to hear conversations and natural sounds, and to notice the way people move and the way the sun reflects in puddle (小水坑).
