That's what i believe too.

I had this conversation with the guy who i share an office with at work. He was so against the idea of pre-determined life. He asked me then why does God choose to to give some people really short life spans (as in dying during childhood) if he is supposed to be a good God and that we should follow in his footsteps. I had told him, it was a random selection and that if all people lived to 115, then the world would be overpopulated and resources which God has given to us to manage would diminish.

He asked why so many children from his family (back 200 years ago) died at such a young age due to illness? Survival of the fitest.

How does God choose who dies young and who dies when they are 105?

PS thanks for the link - i'll read up on it.
