Sleep researchers have used weighted blankets since the 1970s to help children with autism, a kind of mental problem, and adults with sensory problems. They appeared on the market in the1990s, but most were only used by people with special needs.

Things changed a lot in recent years. Companies started focusing on what they call "people who feel anxious sometimes"— basically anyone having trouble with modern life's stress. The ads worked: Time magazine even said the weighted blanket was one of the top 50 "inventions" of 2018.

The idea behind weighted blankets is simple. They usually weigh 2 to 13 kilograms— around 10% of your body weight. They use what occupational therapists call "deep pressure stimulation(压力刺激)". The soft, steady pressure on your body makes you feel like being held.

A study of 120 psychiatric patients found that weighted blankets improved sleep quality over four weeks in people with some health problems, like depression , bipolar disorder, anxiety and ADHD. Smaller studies have shown similar results. One found that 63% of adults reported lower anxiety after just five minutes under a weighted blanket, while another study of psychiatric patients found 60% experienced reduced anxiety during their hospital stay.

However, these studies all focused on people with mental health conditions, not the general population that companies are now focusing on. There's not enough evidence(证据) that they do good to common users who don't have mental health problems.

This doesn't mean weighted blankets are totally useless for healthy people. Shift workers— who have to sleep during the day— might find them helpful. They can fight the known health problems from irregular schedules. Healthcare workers, firefighters and pilots need short, useful naps. These blankets could help them fall asleep faster.

If a weighted blanket makes you feel calmer and sleep better, even if it doesn't work like producers say, that's still good. Just make sure you know what you're buying.

Many of the thousands of replies suggested that the majority of the flying public cannot understand why someone would ever choose the middle over a window or an aisle (走廊). But among the majority appeared a few people who endorse middle seats. "In the middle seat I don't feel I should lean one way or another and generally sit pretty comfortably," one person wrote. Another added: "I'm not getting hit by someone walking down the aisle or luggage either."

Kyle Burke, in Florida, said on Twitter that he usually exchanged seats when asked. "I didn't want to sit between a couple that were upset with me," he told The Washington Post. At 6-foot-7, Burke, 41, said he didn't fit well in plane seats, anyway. So, he preferred the middle, which gives him double chance of having a chatty neighbor.

Frederick resident Samantha Jones told The Post by email that she usually chose the middle seat when traveling alone. As a mother of three, "Having personal space is a far-off memory." she said. "Middle seats have the least amount of responsibility," she wrote. "I don't control the window shade and only have to get by one person to get out or to go to the bathroom."

Despite the few fans, middle seats are still not likely to get much respect. "There's nothing good in the middle seat," Scott McCartney, the writer of the journal Middle Seat said. "The position's infamy (臭名昭著) was part of the reason for the journal's name." He added: "People really care about the ‘middle seat', so they are more likely to pick up this magazine on seeing it."

The Irish poet Yeats said, "The intellect (才智出众者) of man is forced to choose: perfection of the life, or of the work." He was wrong. You could have both.

You're noticing that time spent on academic learning is time not spent with friends. That time cost will get worse as you get older, rounded with working, achievement-hunting or family responsibilities. Many achievers have woken up at age 50 or 70, only to wonder where all of their friends and soft memories were.

It is too easy to forget why we are trying to gain money and knowledge. It is for a life well-lived instead of money and knowledge themselves. Smart people make this stupid mistake all the time, in search for the means to an end so much that they forget the end altogether.

The trick is to see your day, not your life, as the place where you carry out your priorities. Every day there will be one more task you could do. Teach yourself to stop even though there's more to do. Think of things you have missed out in your life and promise yourself you won't do them again: "I won't cancel on a friend's birthday" or "I won't speak to my family as though I'm the lead."

Giving slightly less time to work doesn't mean achieving less. I have been lucky to know some seriously achieving people in my life from Rhodes scholars to Nobel Prize and Pulitzer Prize winners. None of them are in their office at 11 p.m. flapping papers. If they were, they would not have such energy for their greatness.

You don't have to choose between life and work since making time for one helps the other. But you have to make the time since how you plan your day is how you plan your life.
