If you find yourself in a waiting room, be it at the doctor, dentist, or chiropractor, do not pick up the magazines lying on the coffee table. You have no idea how many germy people have touched them, and since people go to the doc because they're feeling sick chances are high that those mags have some germs on their pages. If you flip through one, it's a great way to end up sick.
Cold viruses can survive for up to 18 hours on those magazine as well as many other surfaces. So avoid the public pile of magazines at all costs, and bring your own copy of Women's Health instead if you know you'll be tempted to read the one in the office. Or you can always read FitSugar on your BlackBerry.
