Regarding Anoushka's reference to abortion, in my opinion it is an utterly selfish act. BUT when at an early stage of pregnancy when the scan result shows an abnormality, serious defect in the foetus, in that instance abortion has the grace of euthanasia. Ignoring selfish people who think the ailing elders a burden, euthanasia is still a necessary step in particular patients, unconscious & hopelessly beyond remedy.
