Think about how many people touch the items you touch every single day. Let’s talk about a scenario. You get picked up by an Uber and touch a shared seat belt. You arrive at the airport and touch the shared kiosk to check in to your flight. You use a shared pen to write your name and address on a luggage label. You place your hand on a shared escalator rail on your way to the top floor. You touch the shared bins while going through security. You purchase a muffin for later and touch the shared keypad to enter your pin. You sit at your gate and touch the shared arm rest. You board your flight and touch the shared handle of the overhead bin to store your luggage. You sit down and put on your shared seat belt and adjust your shared head rest. Then without thinking, out comes the muffin. Into your mouth.
Want another one? Your 11-year-old child goes to a local elementary school. There, they have shared desks, microscopes, computer labs, door handles, lockers, pencil sharpeners and so on. Some schools even have shared tablets these days. Did we mention he’s a 11-year-old boy hanging around a bunch of other 11-year-olds? Need we say more? Don’t get us started on pre-teen hygiene.
