Mostly, what I have learned so far about aging, despite the creakiness of one's bones and cragginess of one's once-silken skin, is this: Do it. By all means, do it.
'Sblood, you starveling, you elf-skin, you dried neat's tongue, you bull's pizzle, you stock-fish! O for breath to utter what is like thee! you tailor's-yard, you sheath, you bowcase; you vile standing-tuck!
One of the great functions of art is to help us imagine what it is like to be not ourselves, what it is like to be someone or something else, what it is like to live in another skin, what it is like to live in another body, and in that sense to surpass ourselves, to go out beyond ourselves.
