If
 you’re coming off a weekend when you slept-in, you may be setting 
yourself up for a shock when you step on the scale. A new study found 
that the varying sleep patterns known as social jet lag can increase 
your risk of obesity. That’s because getting too little sleep and then 
trying to catch-up disrupts the body’s natural rhythms that also manage

Americans
 are now spending more on electronic books than the hardcover kind. New 
figures show that e-book sales in the first quarter of 2012 topped 
hardcover book sales for the first time. Sales of downloadable audio 
books are growing the fastest. The trends are linked to the brisk sales 
for e-book reader devices during last holiday season. Source Link 
Knowing
 your fractions and long division may seem like kid stuff, but a new 
study says it’s vital to having the skills to compete in today’s work 
world. Researchers found that many adults have trouble with fractions 
and long division. Both are key to math proficiency at a time when 
everyone from factory workers to Wall Street brokers use math every day 
on the job. Source Link
