" There’s a kind of focusing effect that happens when you’re very ill. I saw it with my granddad, when he was slipping away. You stop caring about the big stuff. Your world shrinks down to very small concerns: the way your dressing gown cord presses uncomfortably against your ribs, the pain in your spine, the feel of a hand in yours. It’s that narrowing that enables you to cope, I suppose. The wider world stops mattering. And as you grow more and more ill, your world shrinks further, until the only thing that matters is just to keep on breathing. "

― Ruth Ware , In a Dark, Dark Wood
