1 . A study published Monday found that people who sleep less tend to be fat，and experts said it’s time to find out if more sleep will fight fatness.

“We’ve put so much emphasis on diet and exercise that we’ve failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University.

Monday’s study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased.

“Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights.

“Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said.

“Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added.

“We caution that this study does not set up a cause­and­effect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.”

The study was published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joseph Bass commenting on it and related research.

Inan interview，Turek said some studies have shown the lack of sleep causes declines in an appetiteholding back protein hormone，and increases in another hormone that cause a longing for food.“In addition neuropathies(神经疗法)in the brain governing sleep and fatness appear to overlap(部分重叠)，”he said.

“Fatness has been rising dramatically in developed countries and reached epidemic(流行病)levels in the United States，”it added，“leading to a variety of health problems.”

2 . What Does the Length of Your Fingers Say About You?

Are you the peace-loving type or the ambitious go-getter? Your finger length might be a clue. Take a look at your fingers. Would you believe me if I told you that the length of your fingers in relation to one another can predict your personality? I know that it sounds like one of those silly tests you see on Facebook, but I have to admit that it is exactly correct for me. Here’s how it works.

Look at your three middle fingers of your hand. Is your index finger longer than your ring finger? Is your ring finger longer than your index finger? Or are the two of the same length? Find the situation that best matches your hand and see if what follows is an accurate description of your personality.

Longer ring finger: The Sweet Talker

If your ring finger is longer than your index finger, research shows that you’re likely a charming type, and you can probably talk yourself out of any situation. Others often find this personality type irresistible and will go to great lengths to help you. You’re more likely to take risks, and you’re good at problem-solving. People in this category make great engineers, soldiers and crossword-puzzle solvers.

Longer index finger: The (Over) Confident One       

If your index finger is longer than your ring finger, chances are you are full of confidence—possibly even to the point of being over-confident and proud. You are not necessarily introverted (内向的), but you do enjoy time to yourself, especially when you’re trying to complete a project. You are a dream pursuer who can make things happen, but you may be shy when it comes to taking the first step in a relationship. You are also probably happy with what you have, but you’re always wishing for more.

Index and ring finger are of the same length: The Peacemaker

If your index finger and ring finger are roughly of the same length, you are likely to avoid conflict at all costs and seek to keep the peace in your relationships. You are well-organized, faithful and sympathetic. But deep down under all of that caring and peace-loving, you also have a hot-tempered side that can appear unexpectedly when you’re pushed too far. You will try your hardest to avoid a fight.

How well do these descriptions match your personality? I was surprised at the accuracy in my case, but I’m not going to tell you which one it was!
