" Something terrible happened during those forty-four minutes... Death. I realised it was real. I would die one day. Kat would die. Mum would die. Dad would die... It was not a question of if but when. Of course, I'd known death before. But during those fifty-four minutes I really knew it. That's when I realised there are two kinds of knowledge: shallow and deep. You can know something in theory but not know it in practice ...I thought of the long chain of all the days of my life and wondered how far along that chain I'd already got. Was I still just starting, halfway along, or nearing the end? "
