At the beginning of the Manic Street Preachers song "4st 7lbs," a girl is heard saying: "I eat too much to die. And not enough to stay alive. I'm sitting in the middle waiting."
The lyrics are about anorexia, written by Richey Edwards, who himself suffered from the disease, at one point surviving on a single bar of chocolate a day.
While anorexia means "loss of appetite," those suffering from it in fact have normal appetites, but they exercise extreme control over their eating.
