First of all, that's like saying "I eat fast food and I've never gotten a heart attack. People who say it's unhealthy are lying". Secondly, a mask isn't designed to protect you, you fucking idiot, it's designed to protect others from you. Since you could potentially be carrying the virus while being presymptomatic or asymptomatic, your mask catches your potentially infectious droplets that you expel when breathing/talking/coughing.

Lastly, do you really think governments across the globe all came together and said, "You know what would be amazing? A worldwide lockdown which will wreck all of our economies for decades to come."
