Over our life span all the debt the we wracked up we pay off with the end of our life. 

But within that life all we do is keep ourselves alive. We eat, sleep, go to work... is there even any enjoyment to life when I know that I'm not going to be alive in a couple decades?

What's the point to living if this struggle will go wasted? No one will know me after I'm dead. 

When I think about it, life is an interesting debt we pay by dying.
