In literary contexts, the figure of a man quite advanced in life or simply a reference to an old man: Familiar figures at New Years are the senex, a graybeard seeing the old year out and a baby welcoming the New Year in.

Translation: "An old man is a boy again" or "old age is considered a second childhood for some elderly men": The grandchildren of the old man kept him so busy that he told his daughter-in-law that he really understood what the Latin expression Senex bis puer means because he was so involved with the children.
