I don't think it's controversial at all. Nobody gets out of life alive. If I make it to 65 or so, I feel I've had my share. It's all downhill after that point anyway, why would I want to prolong the misery?
An easy statement to make when you're nowhere near 65. I've spent a lot of time in my life thinking about death, and as a result I've come to certain philosophical conclusions regarding it. But I know that philosophy is something that exists comfortably in mind of someone without a gun to their head.
