Honestly, I believe that more than half of you are kidding yourselves. It's very easy to be brave when there's nothing to be afraid of, like now. I, for one, told myself that death was nothing to be feared of simply because it's either a change in existance or NOTHING. Rationally, a person wouldn't be scared of death. But let that thing happen to you, let yourself get into a near death experience, I'm talking about out of body experience. It's not as easy as you think. It'll make you **** scared.
Personally, I can't see myself giving my life for anyone else unless their own state of living greatly affects mine. Dying for a stranger is a definite no.
