If you like texting and are trying to lose weight, a new study found that using texting(发短信) to track diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are using it to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese/fat women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (反馈) and tips.

    Every morning, the women received a text from an automated system that said, “Please text yesterday's personal information of steps you walked and how many sugary drinks you had.” Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    “Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior,” Dori Steinberg, who was responsible for this research, said.

    Steinberg said, “Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cell phone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time.”

    There was once a captain who loved money so much that he cheated his sailors at the end of every voyage and took their wages.

    On the last day of one voyage, the ship was in a small port. It was winter time, and the sea was very cold, so the captain said to his sailors, “If one of you stays in the water during the whole night, I will give him my ship. But if he comes out before the sun appears, I shall get his wages.”

    The sailors had heard about the captain's cheating, so they didn't trust him. But then one of them, who thought that he was cleverer than the captain, said that he would do it. He got into the water, and, though it was very cold, he stayed in it. When it was nearly morning, some fishermen lit a fire on the shore about half a mile away.

    “You are cheating,” the captain said to the sailor. “The fire's warming you.”

    “But it's half a mile away! ”said the sailor.

    “A fire's fire,” answered the captain. “I have won.”

    The sailor came out of the water, and said, “Perhaps you think that you are clever because you have won my wages, but you can't cook a chicken.”

    “I can, ”answered the captain.

    “If you cook this chicken,” said the sailor, “I shall work for you without wages for seven years, but if you can't, you will give me your ship.”

    The captain agreed, took the chicken and said, “Where's the fire?”

    “There it is,” answered the sailor. “On the shore.”

    “But it's half a mile away,” said the captain angrily.

    “ 'A fire's fire' you said,” answered the sailor. “If it is enough to warm me in the water, it is enough to cook your chicken.”

    Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of look the same age!

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says,“ You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli ,”it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

    Watching some children trying to catch butterflies one hot August afternoon, I was reminded of an incident in my own childhood．When I was a boy of 12 in South Carolina, something happened to me that cured me forever of wanting to put any wild creature in a cage.

    We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the trees and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.

    I decided that I would catch a young bird and keep it in a cage and in that way would have my own private musician.

    I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home. I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.

    I had left the cage out on our back porch, and on the second day of the bird's captivity(囚禁) my new pet's mother flew to the cage with food in her mouth. The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.

    The following morning when I went to see how my captive was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened! I had taken excellent care of my little bird, or so I thought.

    Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time, hearing me crying over the death of my bird, explained what had occurred. “A mother mockingbird, finding her young in a cage, will sometimes bring it poison berries. She thinks it better for her young to die than to live in captivity.”

    Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.

Extreme athletes have been using wingsuits (翼装) to fly for many years. However, the pull of gravity makes it impossible to speed up or fly higher. To push past the limitations, Peter Salzmann teamed up with German car maker BMW. The result is an electrified wingsuit, which allows flyers to rise to higher altitudes at the speed of up to 186 miles per hour!

The 33-year-old professional wingsuit pilot first thought of creating the design in 2017, "At the time, I was developing suits for skydiving with a friend," he explains. "One evening after a day of testing, we threw out lots of ideas about how we could improve performance. One of them was a supporting motor-and it's an idea I just couldn't shake off. I found the idea of being able to jump from my local mountain wearing the wingsuit and land in my garden exciting."

To help with the process, Salzmann reached out to the experts at BMW's Designworks Studio. It took the team three years and multiple test jumps to perfect the design. The result is an updated version of wingsuit with two 5-inch propellers (螺旋桨), Powered by a battery, the propellers can be controlled using an on/off switch and even stopped mid-flight using the emergency button, if the flyer encounters an airplane or a flock of birds.

On November 6, 2020, Salzmann, wearing his hi-tech suit, leaped from a helicopter from an altitude of 10,000 feet to soar around the mountain peaks. The expert pilot fired up the electric motors and rocketed forward, gliding above four mountain peaks. The task completed, the pilot opened his parachute (降落伞) and gently landed.

It is unclear if Salzmann and BMW plan to make the electrified wingsuits available to the general public. But, one can always hope!
