Good news! For those of us who do all of the house cleaning [1] without help from maids or cleaning services, we're saving more than money. We might also be extending our lifespans! According to an article in Prevention, by simply [2]"vacuuming, mopping floors, or washing windows for a little more than an hour, the average person can burn about 285 calories, lowering risk of death by 30 percent, according to a study of 302 adults in their 70s and 80s." I like the sound of that. And now, I'm going to go get out the Dyson [3] and do some vacuuming.
