Big surprise.  One in three people have not kept their New Year's resolutions.  I bet it's more like three out of three. But a new study says even people with the best of intentions to get heart-healthy in the new year become discouraged after just a handful of long runs or drop their gym memberships after a couple of sessions. Gretchen Wells, MD, PhD, director of women's heart health at the University of Kentucky's Gill Heart Institute, emphasizes in a new video to help people not to give up.

"That doesn't have to come with a gym membership or fancy, expensive equipment. A brisk walk can be just as effective in reducing heart attack risk." In fact, said Wells, even completing household chores like vacuuming or mowing the lawn can take up a significant chunk of that goal....

Research has shown that what a student expects to learn and how they expect to do in a class actually has an impact on their learning, professor Angela King has found. For example, she says at newswise.com, a student might take a divisional class and assume they will get an A because it’s viewed as their “easy” class. “They are already calculating their GPA based on that A and will do whatever it takes to get that A, while a student who takes a class perceived as more difficult, like an organic chemistry course, just wants to pass the class.” And sometimes that means they settle for a C, she added, when a little more effort or an alternative study method could help them improve their learning, and their grade...
