In the sun room of his Darwin home, Bob Dent, 66, finished his lunch and a glass of beer and lay down on the couch. On the floor out of his sight but attached to him by an intravenous strip lay a syringe driver containing a little dose of drugs. Nearby, his wife, Judi, waited with his doctor. The phone was disconnected. In the silence of warm Sunday afternoon, the only noise was the sound of a pump starting. In sequence as planned, the drugs emptied into Dent’s cancer-ridden body. Within seconds, he was asleep. A few minutes later, he was dead. Diagnosis was prostate cancer in 1991. Dent began his journey to death several weeks ago. After obtaining the three signatures required from his own doctor, a cancer specialist and a psychiatrist and observing the nine-day cooling-off period, Dent was free to choose the time of his own passing. It was about 9:00 a.m. on September 22 that Dent finally made his decision to finish the journey. In a letter released after his death, Dent appealed to those who attacked his decision: “If you disagree with voluntary euthanasia, then don’t use it. But don’t deny me the right to use it if and when I want to”.
