Can you recycle your old undergarments, like underwear and bras? Yes, you can. Believe it or not, Goodwill takes any condition undergarments, as long as they are clean. If they are in good enough shape, they'll sell them in their stores. If they are torn or threadbare, they get sold to scrap fabric dealers who recycle them into new cloth industrial products. But here's something you may not know: If you wear 100 percent cotton undergarments, you can compost them. Just cut off the elastic parts and cut the cotton fabric into small pieces. Toss the scraps into the compost, and in no time flat, they'll break down into beneficial mulch for your garden.

Is it greener to shop online or at the store? The answer depends how far you drive. If you live near stores that are in close proximity of your house -- less than 10 miles away -- buying locally is the greener way to go. But if you drive more than 20 miles round trip to a store, buying items online will be more environmentally friendly and probably more convenient to you. Even with overnight air shipping, The Center for Energy and Climate Solutions says two 20-pound boxes is more energy efficient to order online and have delivered than driving those 20 miles. The trick to be the greenest is to elect ground shipping and to buy only what you need.

Washing your hands on a regular basis is a good habit to stay healthy year-round. But did you know the key to proper hand-washing isn't what type of soaps you use or how much you use, but the way you wash your hands? Instead of chemical-laden, antibacterial hand soaps packaged in plastic bottles, regular bar soap can be just as effective to get hands clean. The trick is to use warm to hot water (not scalding) and to scrub well and thoroughly. This will eradicate bacteria and viruses off your hands without the use of chemicals. Dry your hands on a clean towel dedicated to drying hands only.
