When my brother and I were young, my mom would take us on Transportation Days.

    It goes like this: You can't take any means of transportation more than once. We would start from home, walking two blocks to the rail station. We'd take the train into the city center, then a bus, switching to the tram, then maybe a taxi. We always considered taking a horse carriage in the historic district, but we didn't like the way the horses were treated, so we never did. At the end of the day, we took the subway to our closest station, where Mom's friend was waiting to give us a ride home — our first car ride of the day.

    The good thing about Transportation Days is not only that Mom taught us how to get around. She was born to be multimodal(多方式的). She understood that depending on cars only was a failure of imagination and, above all, a failure of confidence — the product of a childhood not spent exploring subway tunnels.

    Once you learn the route map and step with certainty over the gap between the train and the platform, nothing is frightening anymore. New cities are just light-rail lines to be explored. And your personal car, if you have one, becomes just one more tool in the toolbox — and often an inadequate one, limiting both your mobility and your wallet.

    On Transportation Days, we might stop for lunch on Chestnut Street or buy a new book or toy, but the transportation was the point. First, it was exciting enough to watch the world speed by from the train window. As I got older, my mom helped me unlock the mysteries that would otherwise have paralyzed my first attempts to do it myself: How do I know where to get off? How do I know how much it costs? How do I know when I need tickets, and where to get them? What track, what line, which direction, where's the stop, and will I get wet when we go under the river?

    I'm writing this right now on an airplane, a means we didn't try on our Transportation Days and, we now know, the dirtiest and most polluting of them all. My flight routed me through Philadelphia. My multimodal mom met me for dinner in the airport. She took a train to meet me.

    After spending three months in and out of the hospital with numerous health issues, Donald Austin had his leg partially cut off. He was relieved to finally be able to go home after just four days recovering from the operation. When he reached his porch, though, the joy drained away.

    Donald thought he'd be able to make it up the steps to the front door on crutches, but his strength and balance weren't as strong as he'd hoped. The wheelchair was too heavy for his wife, Jennifer Austin, to lift up the steps, even when his mom offered a hand to help. Donald ended up on the concrete, the family feeling totally at a loss. They were out of strength and out of options. Just then, a car caught the family's eyes. It had driven past once but was slowly circling back. The stranger, Steven Smith, pulled up and asked if he could help. Relieved, the family watched Smith lift Donald inside and lay him safely on a couch.

    But the Good Samaritan knew there was more to do. Smith figured this wasn't the only time Donald would need to climb those steps. So the next day, Smith, who's an ordinary worker, came back and asked if he could build a ramp(斜坡) in front of the house. With his dad and a couple more helping hands, Smith set up a ramp over the steps to make the home wheelchair accessible. The act of kindness brought the family to tears.

    “This stranger has saved the day for us twice within 24 hours. He also brightened our spirits that had become increasingly dimmed over the difficult months,” Jennifer wrote on Facebook. “There is a sense of optimism back in our home because of his kindness.”

    There are many reasons why people can't get a good night's sleep and as with any other health conditions, things are not likely to improve until you find a way to break the cycle.

    These are some of the main factors that need to be addressed.

    Worry and stress

    We have all been kept awake by many factors that cause worry and stress in our lives. Money problems, relationship issues and work stresses can have you sitting up all night. A useful habit is to download your thoughts at the end of the day. Keep a pen and paper next to your bed and before you go to sleep, write down your thought and worries, create a to-do list for the following day or set down solutions and ideas that relate to work.

    Diet and eating patterns

    What and when you eat can have a major impact on your ability to sleep. Eating too late or indulging in a rich or spicy meal can keep you awake. These foods take a long while to digest and the after effects of indigestion and heartburn are not going to set you up well for a good quality sleep.

    A research suggests that both calcium and magnesium may be linked to poor sleep. Even low intakes of magnesium found in green vegetables, beans, nuts and seeds have been shown to make it harder to stay asleep. Calcium is found in dairy foods, soybeans and green vegetables and low levels have also been shown to make it more difficult to nod off.

    Alcohol and caffeine

    Tea, coffee and energy drinks contain caffeine that helps to stimulate the nervous system and make you more alert, which is great if you need a pick-me-up. Dosing up on caffeine during the day can affect your ability to sleep later on in the evening. Try limiting your intake of caffeine to the morning and switch to decaffeinated options such as herbal teas. Alcohol is a double-edged sword when it comes to sleep. While a little may help to induce slumber, even in small amounts it can cause fragmented sleep patterns.

    Bedroom environment

    “Your bedroom should be dark once the lights are switched off because melatonin, a sleep-regulating hormone, is very light-sensitive. Maintaining the right temperature can also help with sleep as a room that is too hot may prevent your core temperature from going down, which is essential for switching on the sleep mechanism within the body.

    Here's an idea whose time has come: A flu shot that doesn't require an actual shot.

    For the first time, researchers have tested a flu vaccine patch(疫苗贴) in a human clinical trial and found that it delivered as much protection as a traditional injection(注射) with a needle. Doctors and public health experts have high hopes that it will increase the number of people who get immunized(免疫的) against the flu.

    Seasonal flu is responsible for up to half a million deaths around the world each year according to the World Health Organization. A team led by Georgia Tech engineer Mark Prausnitz has come up with an alternative method that uses "microneedles". These tiny needles are so small that 100 of them, arranged in order on a patch, can fit under your finger. Yet they're big enough to hold vaccine for three types of flu.

    None of the study volunteers had serious side effects. The groups that got patches had mild skin reactions that were not seen in the regular needle group, while the volunteers in the regular needle group were more likely to experience pain. Overall, 70 percent of the volunteers who got vaccine patches said they'd rather use them again than get a traditional flu shot. The study authors declared it a success on all fronts.

    The biggest beneficiaries could be people in low and middle-income countries, where flu vaccines are hard to come by. Reducing pain is nice, but other benefits—the patch costs less, is easier to transport, doesn't require refrigeration, can be self-administered and doesn't cause waste of needles—are even better.

    "Microneedle Patches have the potential to become ideal candidates for vaccination programs," wrote Katja Hoschler and Maria Zambon of Public Health England.

    A new study by Chinese researchers has found differences in the brain activity of men and women addicted(上瘾的)to Internet gaming.

    The study says addicted men have lower impulse control compared with women, indicating that men are more likely to become addicted to internet gaming.

    Researchers from Renji Hospital, which is connected with Shanghai Jiaotong University, recruited 105 Chinese participants for the study, which had two groups - one with 32 men and 23 women addicted to gaming, and the other with 30 men and 22 women who were not addicted.

    They completed a questionnaire for gaming addiction, and reported their gaming history and number of hours playing per week. Researchers also talked with their families to collect the information.

    Through FMRI (磁共振扫描), researchers found that men addicted to gaming had lower brain activity in the brain region associated with impulse control, than nonaddicted men. The lower the activity levels, the poorer the impulse control. Addicted women, however, showed no differences compared with the healthy female group.

    Researchers also studied the functional connectivity between brain regions, which were lower in men with addiction than in nonaddicted men, but showed no differences in the female groups.

    Although there are some limitations, the findings suggest that activity levels displayed in the brain region could be biomarkers to evaluate the behavioral inhibitions of gaming-addicted men, they said.

    Gaming disorder was listed as a mental disorder by the World Health Organization earlier this year. People with the disorder have impaired control over gaming and give it increased priority in their lives－to the extent that gaming takes precedence over other life interests and daily activities.
