Why do we not have tech that goes into the arse/bowels and collects shit into a bag, which we then detach after it's full and discard? Like a colostomy bag but for normal people and without cutting a hole in you. That way, going to the toilet would just be emptying or discarding the bag, and you wouldn't need to clean up or sit there for a while if you're constipated or whatever. Would save heaps of time and the bother of having to go to the toilet several times if you've got diarrhoea.
