I dont think anything is worth doing it,I've never thought bout it. I've been dealing with my health for all my life and had a astma(sp) attack and died when I was 15,after seeing how fast you can be gone and leave everyone you love,I'd never even give it a thought and I dont see how others would.
Your point of view is different from 99% of the world, how many people have been dead and revived.
