The term "right to die" refers to various issues around the death of an individual when that person could continue to live with the aid of life support, or in a diminished or enfeebled capacity. In some cases, it refers to the idea that a person with a terminal illness and in serious condition should be allowed to commit suicide before death would otherwise occur. The concept is often nicknamed dying with dignity.
In most countries in the Western world, people do not in fact have the right to die. Suicide is often frowned upon, and euthanasia is only legal in a handful of countries. In some East Asian countries, suicide may be acceptable in cases such as ritual suicide.
