Bon Appétit editor Andrew Knowlton attempts to work 24 hours straight at Katz's Delicatessen in New York City. Katz's Deli, which has been around since 1888, is home to the famous scene from "When Harry Met Sally" and offers the best brisket, pastrami, and corned beef sandwiches in NYC. Can Knowlton survive the hectic ups and downs of the busiest deli in the city that never sleeps?

Men's Health recently published a video on their Gross channel in which host/Editor-in-Chief Matt Bean tested how many germs were on the surfaces of several public surfaces in New York City. They tested subway poles, door handles, LinkNYC kiosks, cell phones, taxi handles, payphones, and surprisingly enough, the absolute worst germ-filled surface they found was on the Citi Bike handlebars. Check out the video to see why.
