Terry knows what lies ahead for himself, as he keeps saying, but when people are suddenly put into that position, ie due to an accident, then they are not in the right mind to say end it now, or not.
My brother has been in a wheelchair for many years, and has good and bad days, he has a c3/4 neck fracture, and has tried to take his life, but on other occasions, has been up, and travelled abroad, but today I learn that my partners brother, had a heart attack, and is on life support. Would I advocate either taking their lives, to prevent suffering? Or is a cure around the corner? My Gal just rang the hospital, and he is in cardiac resus, and 'stable', but poorly..on a ventilator..as I type, so would the best thing to do, turn off the machine? All the heartache that my partner has had in her life, she wants to save him and love him, he's 51 yo...she has lost too many family, I think it's cruel for someone to say, OK end it now, for the Family, but if no family...
I'm living the point that Terry Pratchett makes. My girls brother is on life support. Her parents died, on the same day a year apart, her brothers and sister died, can we save this one? If he dies, she will be wrecked. If the decision comes to turn off the machine, that's my decision.
