A quote
That is what I remarked to my dear Paulina, who always urges me to take care of my health. I know that her very life-breath comes and goes with my own, and I am beginning, in my solicitude for her, to be solicitous for myself. And although old age has made me braver to bear many things, I am gradually losing this boon that old age bestows. For it comes into my mind that in this old man there is a youth also, and youth needs tenderness. Therefore, since I cannot prevail upon her to love me any more heroically, she prevails upon me to cherish myself more carefully.
