Do they think we are all stupid?

[Chris KC]

While we are down here it is perhaps of interest to reflect that until around the 6th century nobody used toilet paper at all; it wasn't commercially available in the US until 1857, and even today perhaps 75% of the world's population manage OK without it. Quite why it is seen as a household necessity is thus open to some question.

There is much of interest in the historical section of the Wikipedia entry: https://en.wikipedia.org/wiki/Toilet_paper
