Jen has looked back at this Jen often, thought wistfully that she didn’t know how great she looked. She’d focused on her strong nose, her wild hair, but, look: bright, clear skin. Cheekbones. Youth. You can’t fake it. There isn’t a single line on her face while it is at rest. She brings a hand to her skin, which yields like bread dough, springy and full of collagen, not the crêpe paper that awaits her at forty.
