The point is that one's got an instinct to live. One doesn't live because one's reason assents to living. People who, as we say, 'would be better dead' don't want to die! People who apparently have everything to live for just let themselves fade out of life because they haven't got the energy to fight.

It is my experience that no one, in the course of conversation, can fail to give themselves away sooner or later. Everyone has an irresistible urge to talk about themselves.
