Article: Air traffic controllers in the US have been advised to take 26-minute naps , after a series of accidents involving workers falling asleep. Now the National Transportation Safety Board (NTSB) is calling for "controlled naps" during nightshifts . NTSB member Mark Rosekind said that a 26-minute nap would improve performance by 34%. He believes that beyond the aviation industry, other professions, such as motoring and machinery, also carry obvious risks. But other experts doubt whether 26 minutes is the appropriate napping time. It's a bit too long and risks you falling into a deep sleep, says Jim Horne, director of the Sleep Research Council. He said, "A nap of about 15 minutes is best; once you get beyond 20 minutes, you risk a deep sleep and you can be much more tired when you wake up. Therefore, we suggest that a nap be combined with a cup of coffee so that you can enjoy an effective sleep before the caffeine takes effect in 20 minutes. However, this method only works on those who have had a poor night's sleep. If you haven't had a sleep the night before, this method won't be enough to make you fresh." Health writer, Linda Wasmer Andrews, also believes that 26 minutes is too long. She says a nap between 10 and 20 minutes is enough, and the timing of the nap is also important. Putting your head down too early means your body may not be ready to sleep yet, but a nap that is too late in a day might make it harder to fall asleep. Early afternoon is often the best time, between l pm to 3pm, when people experience a post-lunch decrease in energy.

Article: Sitting at a desk in a classroom all day can be pretty boring. The teachers at Ward Elementary in Winston -Salem,North Carolina ,picked up on that and traded in their students' desks for exercise bikes as a part of their Read and Ride program! The Read and Ride program began five years ago.One classroom has enough bikes for every student in any given class,and throughout the day teachers bring in their students to the room to ride them and read their books. Even regular classrooms have one bike in the back of each room for students who just can't sit still to use to help them burn energy in a good way. Students love being more active! Teachers enjoy seeing students eager to read.Parents appreciate stronger,smarter children.Headmasters value this effective and cost-free program."Riding exercise bikes makes reading fun for many kids who get frustrated when they read.Thus,they have a way to release that frustration while they ride,"said Scott Ertl,who started the program."As we can see,everyone wants to promote literacy and lose weight! But many students who are overweight struggle with sports and activities since they don't want to always be the last or lose with others watching on the playground.On exercise bikes,however,students are able to exert themselves at their own level--without anyone noticing when they slow down or take a break." As it turns out,not only are the bikes helping the students burn calories,they're also helping them learn better and stay focused.At the end of the school year the school analyzed testing data and found that students that spent more time reading and riding did more than twice as well on reading tests than their fellow students who spent the least time in the program.
Answer: To help the overweight students keep fit.

Article: I wrote a business plan the other day. I gave it to my husband for suggestions. After reading it, he said, "I don't think this is up to your usual standards." I said, "I need more information. What doesn't work?" He said he wasn't sure. I then took the letter and reread it. He asked, "How about if I look at it again and make notes between the space?" I agreed. A half hour later I looked at his notes and told him he didn't understand the situation and what I really wanted to express. He shrugged and said OK. I took the letter and went back to my computer and again revised. As I was writing, I could see my letter improving based on his suggestions. When I finished, I proudly handed the letter back to my husband. He read it for the third time and said, "It's still not right but I couldn't exactly say." I was a little annoyed and then told him I was the writer and I had seen some goofy letters he sent out. But I picked up my letter and went back to the computer. After an hour of revisions, I went back to my husband apologetically with letter in hand. I told him I was sorry for what I'd said and asked if he would please read the letter again because I did value his contribution. Being a very patient and kind-hearted fellow, he once again read my letter and declared that it was fine. This all leads me to the following: When you ask for advice on a project, be appreciative and grateful. Understand that the advice and suggestions you get may be negative. Understand that it may mean more work for you. And keep in mind that the final responsibility for the project is still yours. So be modest and thankful even if he or she has noted some problems.
Answer: To ask him to give her some advice.
