An international nongovernmental organization calling for terminally ill patients' right to euthanasia convened a conference in Tokyo on Thursday to discuss living wills. The 15th World Conference of the World Federation of Right to Die Societies consists of 38 member societies in 23 countries and will last four days.

The group believes that people should be allowed to decide when and how to die, including the right of patients with terminal illnesses to refuse any treatment that would prolong their lives.
