One should avoid hospitals like the plague. A patient is always just one step away from being an unwitting guinea pig to some new and untested method. Also, it is quite likely in the crappy National Health Service (in Britain) that one will contract a disease while in hospital because the doctors can't be bothered washing their hands, and the staff don't clean the place properly.
Many doctors are fascistic Christian nutters. If they sense a lack of Jesus in you, they will secretly not treat you properly and might even try and kill you.
If you can't get private insurance, don't go to a hospital.
