"I live like an old man. I read the papers a little, a few pieces out of books, I set down a few notes, I keep warm, and, often, I nap." (Je vis comme un vieux. Je lis un peu des journaux, des morceaux choisis, j'écris quelques notes, je me chauffe et, souvent, je sommeille.)

Jules Renard, Journal (March 2, 1905; tr. Louise Bogan and Elizabeth Roget)

That sounds like me all right, especially the keeping warm part. (Simply old, not even Dylan Thomas's 37-horrors turnip-sloth anymore. Tempora/Mores.)
