Another reason to ditch disposable plastic water bottles: They can make you look older. New reports show the pursing of the lips around a bottle of water repeatedly can actually form deep wrinkles around our mouths. The look is similar to a lifelong smoker who also purses his lips around a cigarette. To avoid having an older-looking mouth, keep drinking water -- just do it from a glass. It's another reason to invest in an inexpensive water filtration system and to skip the ecological nightmare of plastic bottled water.
