Lewis Thomas, “The Long Habit,” in The Lives of a Cell:

In a recent study of the reaction to dying in patients with obstructive disease of the lungs, it was concluded that the process was considerably more shattering for the professional observers than the observed. Most of the patients appeared to be preparing themselves with equanimity for death, as though intuitively familiar with the business. One elderly woman reported that the only painful and distressing part of the process was in being interrupted; on several occasions she was provided with conventional therapeutic measures to maintain oxygenation or restore fluids and electrolytes, and each time she found the experience of coming back harrowing; she deeply resented the interference with her dying.
