Euthanasia (from the Greek εὐθανασία meaning "good death": εὖ, eu (well or good) + θάνατος, thanatos (death)) refers to the practice of intentionally ending a life in order to relieve pain and suffering.

There are different euthanasia laws in each country. The British House of Lords Select Committee on Medical Ethics defines euthanasia as "a deliberate intervention undertaken with the express intention of ending a life, to relieve intractable suffering".[1] In the Netherlands, euthanasia is understood as "termination of life by a doctor at the request of a patient".
