Wife has been feeling "puny" for about a week or so. Finally got to feeling bad enough that we decided a doctor visit was in order. Can't see the doctor without a COVID-19 test because she has the symptoms. Got tested Tuesday. Got a call this morning. She tested positive and I tested negative. She has taken a lot more precautions and been out a lot less than I have. I figured out why. That nurse ran that swab so far up my nose that what they were testing was actually brain matter. That's why mine was negative.
