Bummed that Memorial Day weekend has come to an end? Don't worry -- you're not alone. New (and very depressing) research finds that the natural high you experience on a vacation goes away ridiculously quickly. In fact, even during your vacay, your enjoyment often peaks between 40 and 70 percent of the time in, because you start to get bummed about it coming to an end. And most people find that, within a week of returning to work, most of the pleasant effects of taking time off to go somewhere -- feeling relaxed, upbeat, etc. -- have gone away completely. My next vaca is in August.. I'm counting the days! Lol Happy Tuesday, folks!
