It's up to the individual to decide what's right or acceptable for themselves.
And that would be well and good EXCEPT the act of simply breathing out, if you are infected and contagious (usually before symptoms show) means that you can infect every individual within 4-5 meters of you. You might feel you are able to handle the disease. At 75, I am reasonably healthy, but know I'd probably get pretty sick. Hubby had quad by-pass this year with complications (why we spent the summer in AZ), and he's diabetic with only ~30% kidney function left - - it I get sick because I was near you, and give it to him, then he will die.
