Check out the history of bird migration science. There was everything from birds going to the moon for winter, swallows burrowing in the mud, transmorphing to different species, up to the 19th century

I did some travels in places where bidets are common, here’s my take:

• Egypt - basically a brass pipe targeted at your hole, everyone shitting oh it - no for me
• Italy - standalone, you have to jump over - impractical, takes too much space
• Japan/Korea - toilets from space, heated seat warm, water and dryer - comfy, but you need electricity, and if it fails, expensive
• Finland - a shower attached to the toilet’s water intake - just cold water, but it’s fine, that’s the easiest to install and use
