Paper hasn’t always been the material people have used for wiping themselves after using the toilet. Historical methods include using wool, hemp, rags, lace, water, snow, stone, sand, seashells, grass, leaves, moss, ferns, seaweed, plant husks, wood shavings and fruit skins!​ Must say the thought of seashells makes me wince a little.

Flush toilets work well because of the ‘S bend’. This S shaped tube connects to the sewer plumbing under the toilet and its shape creates suction which literally pulls the water and waste out of the toilet bowl and into the sewer without letting any waste or dangerous gases rise up into the bowl.

If Anglian Water put all the rubbish it collected from sewers into skips and stacked them one on top of another, they would reach almost as high as Mount Everest.
