Guy De Maupassant said this quote

For some years he had felt weighing on him the burden of loneliness which sometimes overwhelms old bachelors. He had been strong, active and cheerful, spending his days in sport, and his evenings in amusement. Now he was growing dull, and no longer took interest in anything. Exercise tired him, suppers and even dinners made him ill, while women bored him as much as they had once amused him.
