Juggling many projects is inefficient, according to research at the University of Michigan. When people were asked to switch back and forth between tasks, such as doing math problems and sorting pictures, they took longer to complete each job than when they worked on them one at a time. "When you shift your attention from one thing to another, you have to remember where you stopped and then start your train of thought again," says David Meyer, Ph.D., an author of the study. "If you have tasks that can be done in modest chunks of time--say, 45 minutes--it's better to stick with just one from start to finish." 4 MEMORIZE ANYTHING WITH THIS QUICK TRICK

Maybe you've thought of something for your to-do list but don't have paper and pencil handy, or you need to remember talking points for a meeting. Try this proven memorization technique from a study at University College in London: Picture yourself walking down a road you know well, and then put images of the things you need to remember at specific spots along the route. When it's time to recall those items, mentally retrace your steps. The researchers found that many people with good memories aren't more intelligent than the rest of us, they simply use savvy spatial techniques. 5 lower your cancer risk: cut meat and dessert
