"My face set to a grim and determined expression. I speak in all modesty as I say this, but I discovered at that moment that I have a fierce will to live. It's not something evident, in my experience. Some of us give up on life with only a resigned sigh. Others fight a little, then lose hope. Still others--and I am one of those--never give up. We fight and fight and fight. We fight no matter the cost of battle, the losses we take, the improbability of success. We fight to the very end. It's not a question of courage. It's something constitutional, an inablity to let go. It may be nothing more than life-hungry stupidity."
