1 . Are you relatively skinny but growing a “beer belly”?
Then don’t be surprised at your next checkup if the nurse measures your waistline to determine your healthy weight. That’s because research is showing that a protruding (鼓出的) belly may be a sign of VAT — a dangerous form of fat around organs deep inside your body. “Studies confirm that visceral (内脏的) fat is a clear health risk,” said Dr. Tiffany Wiley, a senior expert at the National Institutes of Health in Bethesda, Maryland. Unlike the fat just under your skin, visceral fat raises your risk for heart disease. Experts think that’s because visceral fat raises blood pressure and inflames (使发炎) tissues and organs.
However, you can’t assume you’re safe from visceral fat if your overall weight is healthy, experts stress. That’s because you can have dangerous visceral fat even if you’re not considered overweight — and not have any visceral fat even if you are overweight.
How do you know if your stomach is protruding into dangerous size? Do a check. Non-pregnant women with a waist size greater than 88 cm and men with a waist larger than 102 cm, are at higher risk according to the US Centers for Disease Control and Prevention. If you’re Asian, it drops to 80 cm for women and 90 cm for men. But it is only a rough measure. “The only sure way to know is to check your visceral fat levels on a CT scan or MRI,” say experts.
According to the AHA committee, the most salutary physical activity to “shrink” belly is aerobic exercise. Aerobic means “with oxygen”, so aerobic exercise increases your breathing rate and promotes the circulation of oxygen through the blood. This type of exercise makes the heart work more effectively and improves its ability to move oxygen-carrying blood with every beat. Speed walking, jogging, stair climbing, cycling and swimming are all examples of aerobic exercise.
“However, more studies are needed to determine the best physical activity, food and other lifestyle changes to reduce heart disease risk,” Dr. Tiffany Wiley added.

2 . Bad weather drags your spirits down. There’s nothing you can do about the weather.
◆Find things to enjoy about winter.
A snowy, icy, cold, or rainy world can be beautiful and often has sounds and smells of its own. If you’re an artist, or photographer, winter provides a great deal of inspiration and different colors to work with.
◆Take part in winter activities.

Winter comes with the shortest days and lowest light of the year. Go out if you can. If you can’t, or if you’re so far from the equator as to have little or no daylight, use bright lights and perhaps light or white walls.

6 . Exchanging old-fashioned postcards with random strangers around the world is great fun. And for me, it’s sending not just any postcard, but one in particular that seems to resonate (共鸣) with people everywhere.
The Postcrossing project was created by Paulo Magalhaes in 2005. He liked getting mail — especially postcards. He thought others did, too — but how could he connect with them? That’s when he came up with the idea of an online platform (postcrossing. com). There, postcard lovers like me can sign up to send a postcard to someone who has registered (注册) online, and receive a postcard in return.
Along with a randomly selected address, participants get a unique code to put on the postcard. When the postcard arrives, the recipient registers that code with the site, which then causes the sender’s address to be given to another Postcrosser in turn. In practice, this means that for nearly every postcard I send (a few get lost in the mail) I get one back. And since I never know who will be sending me a card or where in the world they live, every trip to the mailbox holds the potential for a wonderful surprise.
At the last count, there were more than 690,000 Postcrossers in 211 countries, representing nearly every race and religion on the planet — and the cards they’d like to receive are nearly as diverse. I’ve seen requests for postcards featuring maps, animals, Benedict Cumberbatch (an actor), and the color green. But no matter how lengthy or unusual a particular Postcrosser’s list of requests may be, somewhere, in nearly every card, is a sentence like this: “Please send me a card that represents something unique or special about your country.”
I love to see that request. To me, the opportunity to share what I love most about my country and to learn what other people love most about theirs is the heart and soul of this activity.

9 . More than 25 years ago, Saroo Brierley was one of many poor children in rural India. One day, he played with his brother along the rail line and fell asleep. When be woke up, finding himself alone, the 4-year-old decided his brother might be on the train he saw in front of him—so he got on.
That train took him across the country to a totally strange city, where he did not speak the language. He lived on the streets, and then in an orphanage (孤儿院). There, he was adopted by an Australian family and flown to Tasmania.
As he writes in bis new book, A Long Way Home, Brierley couldn’t help but wonder about his hometown back in India. He remembered landmarks, but since he didn’t know his town’s name, finding a small neighborhood in a vast country seemed to be impossible.
Then he found Google Earth—a digital mapping program. He spent years searching for his hometown in the program’s satellite pictures. In 2011, he came across something familiar. He studied it and realized be was looking at a town’s central business district from a bird’s-eye view. He thought, “On the right-band side you should see the three-platform train station”—and there it was. “And on the left-hand side you should see a big fountain”—and there it was.
Everything just started to match.
When he stood in front of the house where he grew up as a child, be saw a lady standing in the entrance. “There’s something about me,” be thought—and it took him a few seconds but he finally remembered what she used to look like.
“My mother looked so much shorter than I remembered. But she came forth and walked forward, and I walked forward, and my feelings and tears and the chemical in my brain, you know, it was like a nuclear fusion (核聚变). I just didn’t know what to say, because I never thought seeing my mother would ever come true. And here I am, standing in front of her.”
