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.
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.
