I mean, you do you, but I'd rather have the minor inconvenience of breathing through a mask and save myself an illness than take a 1 in 4 chance of having impaired lung function a year later. 

“At 1 year of follow-up, 25% of the 349 participants had impaired lung function, including 11%, 22%, and 48% of those with mild, moderate, or severe/critical COVID-19, respectively.”

If you've heard #COVID19 is just like the flu, you were misinformed. Be a bit safer, please.
