my elderly father has an illness similar to psp but he does not have dementia so he is fully aware of his declining health. He is in a lovely care home but has to remain in bed as he has bed sores. when he eats or drinks he chokes a lot and has started to refuse to eat. the home wish to now discuss force feeding him but we feel he is not eating as he is loosing the will to live. His wife of 60 years died last year and other than his family visiting every day I think he feels he doesn't have anything to live for.should we allow him to be force fed or allow him to slip away as we believe he wants to?
