Dance Dance Revolution Exercise Study
krf writes "Gamasutra reports that researchers in West Virgina are doing a study on using DDR to fight childhood obesity." From the article: "The study, which is currently budgeted at $60,000, provides each of the selected 85 child participants with a game system, copy of the game, and dance pad."
Back in my day, my mother kicked us kids out of the house to get some "god damned peace and quite".
So, the trick is for parents to have more than one child. Said children will fight over limited resources (television, Nintendo, Legos, etc.). At which point one or both parents will become pissed off. The children will then be kicked out of the house and left to their own devices. (In our case, it was playing baseball except with apples from a nearby tree. It was messy.)
