That’s a radical idea, but you’re right that if we’d always been like that no-one would question it, and it would be so more convenient!
I’ll take it one step further and say it would be a lot easier if we didn’t have such complicated plumbing that required 2 completely different systems and exits! Just one, like a bird has, would be so much more practical.
But even if we had to keep two, a disposal system that you stuck your hand/s into, did your business, and then kept them in there to clean up afterwards…yeah I could totally get behind that! So very much easier and more hygienic that the current method.
So, Chief Scientist Poll, it’s down to you to work out how we can evolve to this advanced waste disposal system. Watch out for sabotage from Kimberly-Clark et al. though, you’d be putting them out of business so they’d fight you every step of the way!
