Explanation:
um tbh idk what to answer Imma just say what ik
ok so first of all I didn't get this question well any ways
mask or maybe Face coverings are very necessary to wear on this messed up crisis but Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection and that's doesn't sound good at all right does it ?XD
idk just wrote what came in mind LOL
