If you replace only one thing in your house to save water, think about replacing your showerhead. But how can you tell if your showerhead needs to be replaced or is already efficient enough? Start with a gallon bucket and turn on the shower; if the bucket fills up in less than 20 seconds, it needs to be replaced. When shopping, look for a showerhead that is WaterSense approved; it's a designation from the Environmental Protection Agency that identifies the most water-efficient products in the marketplace. This new showerhead will use less water than your old model.

When choosing between bagged lettuce and a whole head of lettuce at the supermarket, it may seem "triple washed" precut lettuce is a more convenient way to go. But the reality is that many bagged lettuces are up to two weeks old already when they reach your dinner plate, according to Mother Jones magazine. And bagged lettuce costs more: Pound for pound, the convenience of bagged greens costs about 50 percent more. But making your own salad couldn't be easier: Just cut a head of lettuce yourself, soak in a water bath and use a salad spinner to get it dinner-ready.

In the winter months, the mixture of melting snow and ice, deicing salt, dirt and mud can wreak havoc on your shoes. If your leather shoes get stained from the melting mix, the good news is you have 48 hours to clean them to make them look as good as new. After that, the discoloration and stains will set in. To clean them, just make a simple 50-50 solution of water and white vinegar, and dab the shoes clean with a soft cloth. This will remove the stain. Allow the shoes to air-dry, and they'll look good as new in about 24 hours.
