Im convinced it was a bug gone around nationally, or wider. Seen lots with "the cough" including me and a car buddy. The Bowlers didn't seem to get it.

For me the last two days of it included a headache pain in the back of my noggin (unusual), then gone. Easily tired.
Some kids got pnumonia and went to ICU. Glad you are out and about. I'm convinced upright activity is key to clearing & healing the lungs.
Avoiding pnumonia is anybody's guess.
