  • How many days can you use a towel before tossing it in the laundry? Well, the good news in that infectious bacteria and fungi   like the stuff that causes athlete's food can't survive on a towel once it's dry. That's according to Dr, Syed Sattar, professor of microbiology at the University of Ontario in Canada. However, he says that each time you towel off, you rub more bacteria from your skin onto the towel, slowing down the fabric's drying speed and after 7 days, your towel collects enough organic material to form a barrier that actually protects the bad bacteria. So - after week, toss your towel in the hamper.
  • What's the best sleeping position to avoid back pain?--There really isn't one position that's best for everyone, but you can make your favorite sleeping style more comfortable and less damaging on your back. According to Neil McKenna, a physical therapist at the Rehabilitation Institute of Chicago, pillows are the answer.
    Here's how. If you're a side sleeper, draw your legs up toward your chest and put a pillow between your knees. This'll take the stress off your hip joints and lower back, which might be causing your pain. If you sleep on your back, put a pillow under your knees to save 8 hours of back stress. If you sleep on your stomach, put a pillow under your abdomen to keep your lower back from sagging. You'll feel like a champ in the morning
