I have someone in my tree described as an imbecile. He goes through the census described thus but is also employed as a farm labourer. So my guess is that he couldn’t have been too afflicted even if he was only carrying out very menial tasks. He lives with his parents but I lose track of him in 1891, I’ve always hoped that he didn’t end up locked away somewhere 
I had a work colleague who was deprived of oxygen at birth and had intellectual disability but could do cleaning and other menial tasks. His mind was often not on the job and he was easily distracted. In the 1800s he would be described as perhaps a "moron" before the term became an insult. Or said to be "a bit simple". He also used to grab people by the arm a lot and embrace people by hugging them or touching and stroking their face.
