Most of us say we don't have time for exercise. However, many experts say that exercise plays an important role in making our body healthy.
2 . My family moved to St.Paul,Minnesota last year, where the average winter temperature is around 10 degrees Fahrenheit. Once summer ended,everyone went inside to play ice hockey. I’d been on the ice only a couple of times when I was much younger. When I’d fallen and broken my wrist during my second lesson, I’d decided never to put on ice skates again.
Ben,the friend I made in the new city, volunteered to teach me to skate. Even though he was very patient, I was so embarrassed by my clumsiness that I began to make up excuses for not skating.
One day I discovered a faster route home. It took me past a large frozen pond.I noticed a woman teaching a young girl to skate. The girl was attempting to jump and spin in the air. Over and over, she pushed off the ground with the toe of her skate. And over and over, she landed hard on the ice.After I had been watching the girl practice for about a week, one afternoon she suddenly lifted off the ground, spun in the air,and landed on her feet!
The next day I bought myself some brand new skates. Every day on the way home l stopped at the pond and wobbled onto the ice, right next to the girl who had landed her jump.As she perfected her twists and tricks, I taught myself to glide and turmn. It was hard being a beginner,and when I felt I had to fight the urge to simply give up.Instead,every time I went down, I just picked myself up and started over again. Soon I was able to keep my balance and skate more confidently.In just a few weeks,I was actually ready to practice the speed skating, fast stops,and quick turns needed for ice hockey. When I was finally ready to show Ben my newfound skating ability, he told me I should join the local hockey league.I tried out and was chosen for a team. By the end of the season, I was part of a winning team.

10 . At the end of a long day, it’s tempting to dive into your social feeds or Netflix queue the minute you've finished eating. But back before screens took up all our free time, an after-dinner walk was a popular activity. “Italians have been walking after meals for centuries,” says Loretta DiPietro, a professor at the George Washington University, “so it must be good.”
Research backs this up. One study co-authored by DiPietro found that when older adults at risk for type-2 diabetes (糖尿病) walked for 15 minutes after a meal, they had steady blood sugar levels in the hours afterwards. The human digestive system turns food into glucose (葡萄糖). After a meal, glucose floods a person’s bloodstream. Insulin (胰岛素) helps pull that glucose into cells. But for people with impaired insulin activity, too much glucose can remain in the blood, which can cause heart disease and other health problems.
What good does walking do? “The muscles we use to walk use glucose as energy, drawing it out of circulation and therefore reducing how much is floating around,” says Andrew Reynolds, a postdoctoral research fellow at the University of Otago. Reynolds conducted a study of people with type-2 diabetes and found that just 10 minutes of walking after a meal helped control their blood sugar levels. “We saw the biggest differences with walking after dinner time,” compared to other times of the day, Reynolds says. “The production of insulin in response to a meal tends to decrease later in the day. Getting up and moving around at that time was very effective,” he says.
A little post-meal movement may also aid digestion. But more isn't necessarily better when it comes to post-eating exercise. “Exercising muscles pull more of the blood flow their way during activity, and the GI tract (消化道) gets relatively less,” says Sheri Colberg-Ochs, a researcher at Old Dominion University. “That actually slows down the digestion of food in your stomach during the activity. Anything but really intense exercise would probably work equally well.”
So make like the Italians and head out for a walk after your next meal. Your TV and the Internet will still be there when you get home.
