I think this neuroscience explanation is BS. Teach your children to clean up after themselves and they will as adults. I had chores to do growing up and my mother demanded a very clean house. And my parents didn't wait on me like I was a guest in their house. I was expected to do what I was capable of doing. This same expectation came from our teachers and other adults in the neighborhood. I remember the Catholic school I attended for a couple of years for 5th and 6th grade had a job rotation in the cafeteria so everyone helped out in some way to clean up after lunch. Our Boy Scout leader was very adamant about our uniforms being clean and pressed at meetings and us not depending on mommy to do it for us. I have to wrap this up because something tells me there are dishes in the sink that need washing.
