Sir David Attenborough says he would consider voluntary euthanasia if his life became "wretched".
Asked if he supported the right to die, the veteran broadcaster said: "I suppose I do really, but (only) if you could solve all the problems of dealing with the misuse of such a right."
The 89-year-old told Radio 4's Costing The Earth program that he would consider voluntary euthanasia "if I was compos mentis and I was really having a wretched life".
He said: "When you see poor people, poor in the sense of having some wretched disease, pleading for their lives to be brought to an end, it's difficult to think that they don't deserve to have that right."
Attenborough did admit, however, it was "very complicated" and involved not only medical issues but philosophical issues too.
