The tale (a Hadith) tells that Muhammad saw a shepherd going to pray, while keeping his Camel untied. He asked the shepherd why he kept his camel untied and the shepherd told him: “I put my faith in Allah, that the Camel won’t escape”. So Muhammad told him, and I paraphrase: “Dude, it doesn't work that way! Camels can escape due to nature’s whims. So: put your faith in Allah, but, for the love of God - tie your Camel.” (I am an Israeli, agnostic, non-religious, Jew but I think I can borrow useful memes from Islam, or whatever, if I think they have merit, right? See Ad-hominem.)
As much as I admire God for his wonderful creation, I still have to help myself, and help him help me. I also am not sure whether I will continue to live after I die, so I'd rather not risk it. God’s creation is wonderful, but there's always a risk I'm being toyed by some evil genius (or what Descartes called the “evil demon”) and that reality is not what it seems to be (see Descartes’ “I think therefore I am” thought experiment, and naturally The Matrix concept from the first “The Matrix” film). Alternatively, it is possible that God does not exist, and reality is simply whimsical and random, but still enabled the creation of life, intelligence, and finally - human consciousness.
So it may sound far-fetched to you, but I don't want to die - not now, not in a thousand years - not ever. Maybe it's a scary thought, but I have accepted it now, and wish to enjoy youth rejuvenating biological immortality. And I don't want me or any of the living heroes I admire in the present, both those that I know and those that I have only heard about (including some people I have a feud with, but still know are mostly good people), to ever have to die due to old age, accidents, or misfortune.
