Lizz Winstead, Mike Pesca and Melanie Whelan are panelists. The "Daily Show" creator, host of "The Gist" podcast, and CEO of Soul Cycle ponder the pursuit of perfection — in cityscapes and on farms, in how we keep time and how we remember. Our fact-checker is A.J. Jacobs. host of the "Twice Removed" podcast.
