what is the status of euthanasia in:
1. you can, without recrimination, commit suicide but cannot have assistance (1961 Suicide Act), although some argue it's cruel to make someone live just because they cannot commit suicide themselves
2. movement towards 'proxy empowerment' and living wills for physician assisted suicide (rejected by pro-life movement)
3. no uniform law, doctor may discontinue life support at patient's request (and this doesn't constitute assisted suicide) and you can refuse extraordinary treatment in advance if incapacitation occurs
4. euthanasia legalised but only in conflict of duties between doctor's medical ethics and demands of patient. lots of strong criteria which must be followed, e.g. getting advice of second independent doctor
