'A few years ago, I fall down two flights of stairs, and during a CT scan I can’t remember, I am told that I have a concussion. I return home to my housemates loading in speakers, setting up for a party. Still vomiting, dizzy, mind adrift, I climb into my car, drive forty minutes down the M1, and stumble down the pathway to my mother’s house. I collapse at the door before I can get my keys out. For over a month I lie in my old childhood bedroom, unable to move, my head sore and empty. I become, for these weeks, simply a body.' (Introduction)
