I have a chronic illness and have been hospitalised a few times for it. I enjoy staying somewhere where the nurses and doctors are looking after me, I feel safe, the doctors and nurses are generally lovely, it can be peaceful if other people on the ward are quiet and I get fed (very nice meals in my opinion which I get to choose off a menu), don't have to cook or think about what's for dinner, and can lie there all day and night, albeit in pain sometimes, but the strong painkillers often see to that. I do feel for people who are in hospital for long stays and serious illness, end of life, etc.
