Yes. A retired professor emeritus of anesthesiology in my department, in his 80s, bedridden, and on dialysis, told our department chair that his life had become too unpleasant and boring to continue with the round the clock routine of treatments and tests that would be his lot until he died. He directed that the dialysis machine be disconnected and died comfortably shortly thereafter.
