You know, I've often noticed what appears to be brilliance when someone

In saying that, the overall point of your post, Bill, is well made. Men and women seem to find the idea of sphincter toileting a particularly private thing. That being said, the amount of people I've come across who think that toileting is, in some way, amusing and/or clever, still amazes me.

It's quite natural, requires no effort (in fact, effort
not to is sometimes expended) and is a necessity if one doesn't covet toxic shock. It's little wonder people find it meditative when you consider there is no intellectual engagement.
