Well you know in the not so distant past, people would throw new borns into a pool or well to test their strength and desire to survive. They had a belief that if the child were to drown then they were not meant to be part of the ongoing culture. If they lived, they made it even stronger.
So, with today's mechanized environment, maybe this would be some kind of equivilent.
Hey throw the little tyke on the spin cycle! Kick that dryer up to high tumble! LOL
