I'm a speech and language therapist, and I work in an acute NHS hospital, on a stroke unit some of the time. I see a lot of people die. My personal opinion, not professional, is that modern medicine often keeps people alive longer than they should live, and that the extra life they have is not what they would have chosen if they had been in a position to make a well-informed choice before they were ill.

Whatever happens, the NHS will look after your father. You need to make sure someone looks after you.
