Bell managed to find a worm expert, Patricia Naidu, who spent some quality time with the worms in their ultra-rich environs. (I couldn't help but imagine Particia as the perky Karen Allen with Harrison Ford among the snakes in the Well of Souls.) Patricia has gone on record saying that the worms indeed did appear "happy" with their new lot in life -- this based primarily on the fact that they were healthy and breeding with gusto.
Being on the toilet is one of the bright spots of my day. But now I really want one of these worm toilets. I'd be even happier taking a shit knowing that I was bringing happiness to so many others.
