I'm a 70-something mile a week guy who runs kinda lousy 5ks, and marathons in the 2:45 range at best. Me and my kid got this thing as soon as it came out. I was totally laid up for 3 days, and it took a total of about 10 days for me to recover completely, as though nothing had happened. My seven-year-old kid ran a fever and coughed incessantly for two weeks. He responded to OTC pain reliever and fever reducer, and he pretty much went about his business, bothering everyone around him with an incessant cough.
This was *just* at the beginning of the COVID-19 scare. We joked at the time that we all had the virus. Looking back at all the craziness that has since ensued, we probably should not have been so cavalier.
