No, possibly not, even if it´s an intriguing idea. But after 50 years, you would naturally grow tired of living. I say naturally because I believe that we are mortal and have such short lives for a reason. Can you imagine the situation when you have tried everything in the world, been everywhere, you are incredibly tired of living and yet you CANNOT DIE no matter how you try? It would be dreadful! It would make you depressive and full of pain. You´d end up trying to die various ways - with no results. So if somebody asks me if I would like to be immortal, then I am going to say: "NO".
