If you are one of those people who put on a shirt and pair of jeans late in the day, and then throw them in the dirty clothes pile a few hours later, ask yourself how dirty they really are. Does worn for a few hours really mean dirty, usually not unless you went swimming in a mud puddle. Just fold them back up, and put them on a couple days later, for a few hours. Add a couple extra swipes of deodorant though You'll be doing half as much laundry, and we know how much energy that takes (from you and the power grid).
