Maybe you pop vitamins supporting brainpower, or stock upon these foods that boost brain health. But new guidelines from the American Academy of Neurology suggest there's something better you can do to keep your mind sharp.
A quarter of adults aged 80 to 84 experience mild cognitive (认知的) impairment, according to AAN. To address the widespread problem, a group of neurologists and Alzheimer's (阿尔兹海默氏症的) specialists went through existing studies to define the best ways to prevent and treat cognitive decline-and you might be surprised by what they included and what they didn't.
Surprisingly, the AAN guidelines don't include any medication (药物) or dietary recommendations. The authors stress that there haven't been any high-quality, long-term studies finding foods or medication can help cognitive decline. The guidelines also say doctors can consider suggesting cognitive training to patients with memory loss but not to rely on it. So far, the report's authors say the evidence is too inconclusive to say for sure if brain exercises, like memory and attention training or problem solving for everyday issues associated with memory loss, are beneficial. Still, these morning brain exercises can't do any harm.
But there was one big discovery from the new guidelines: Exercising just twice a week could improve cognitive decline. One study showed adults with mild cognitive impairment who did resistance training twice a week scored better on executive function and associative (联想的) memory tests than a group that worked on balancing, stretching, and relaxing.
What's more, another study had older adults attend either biweekly health classes or sessions of aerobics, strength training, balance exercises, and multitasking training. Six months later, the ones who'd exercised regularly scored better on cognitive health and memory tests, plus had less brain shrinkage.
AAN now recommends doctors tell patients with memory loss to exercise twice a week to keep their minds sharp. This is the best time to exercise if you want to improve your memory. It looks like you've got just one more reason to clear time in your schedule for a workout — even if it's only on the weekends.

Last month, my husband and I completed what some of our friends considered a foolish task: a 32-day, 5, 232-mile camping trip with children in our Volkswagen van, without ''high-tech'' to occupy the children.
It was the screen less journey that showered me with doubts. But is ''boredom'' senseless? My friend Renee, who has driven cross-country with her three kids eight times, calls boredom the mother of creativity. She's not the only one who sees virtue in blank time. In a recently published paper, researchers at East Anglia University in England concluded that the trance like (发呆的) state helps recharge the mind and is ''central to learning and creativity''. I wasn't trying to make my kids smarter. Neither do I dislike high-tech. But I understand too well the power of mini screens to transform our kids into zombies (木讷的人) .
On Day 1, our 7-year-old son announced ''Texas is so boring!''. The next day, struggling against his seat belt, he yelled he couldn't take much more of this. His 5-year-old sister was better at the long hours playing make-believe with the stuffed animals. On Day 3, he began count mountains and see pandas and dolphins in distant clouds in the Texas sky. I often joined the kids in the back, where we did thumb-and-toe wrestle. With well-known mountains ahead, my husband told the children the past legends of them. ''Arizona is not as boring as Texas,'' our son declared.
I hope the trip gave kids some lazy, unstructured time to learn something about valuing the trip instead of looking for the fastest way to burn it up. I don't always make the right call as a parent but I know that in banning the small screen we made the right choice this time.

Kent was a manager of a furniture agency. His establishment nearly went bankrupt (倒闭）because of the wrong decision he had made. He was so regretful and depressed that he planned to drive to a bar alone to release his emotions.
It was near midnight in an extremely cold winter, and the temperature was minus 9 degrees centigrade. There were few people in the street. Suddenly, a figure of an old madam entered his line of sight. She was standing sideways near a platform, dressed in a plain coat, dragging a suitcase, and holding a plastic bag in the other hand. The slight old lady was seemingly more than 80. She was trembling in cutting wind. Now she kept motioning Kent for a ride. Although Kent was somewhat angry about the old madam's disturbing，he wouldn't like to leave her in the cold night. He noticed she coughed violently and thought that she might be ill and really needed help. So he braked near her.
The madam said, "Would you please take me for a ride? I can offer double fare. . . " Kent interrupted her, "I will charge you nothing! Come on!" The madam pointed to her luggage and said, "Could you put my suitcase into the car?" Kent stepped out and put it in the trunk.
Kent proceeded to drive. He stopped at a petrol station where he wanted to purchase gallons of gasoline (汽油). During the interval they waited in a queue，the madam began her narration, "Could you please send me to the charity house in the suburbs? I want to send them something. I had been given help there 50 years ago. The president and workers were all good guys." She burst into tears，"Now they've all passed away. The life was tough at that time, but we all loved and cared about each other. I've held a desire to be back there again for long." Kent realized the madam was recalling a section of the good missing days. A complicated feeling surrounded him, and he decided to cancel his plan and stay with the old madam.
Paragraph 1 ：
After a two-hour drive，they came to the gate of their destination.
______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2 ：
Hearing this, Kent lapsed into silence, because he knew the rest home was for patients with incurable diseases.
