Zoe Williams writes for The Guardian:
You might get lucky with what they call “compressed morbidity”, a very short period of illness before you die, but you probably won’t. You might, in the event, find the suffering less awful than it looks, in which case you will, of course, retain the right to die in your own time. But the prospect of an enforced period of suffering, of unknowable length, to satisfy the sensibilities of people who may be motivated by a faith you don’t share, or a fear of the law legitimising matricide, which you think unfounded, or some woo-woo sense that the universe must be left to move in its own mysterious way, is not so much unappealing as deeply unjust.
