I'm into my 8th day of Covid, Like yourself I'm a reasonably fit guy for my age 60+ I keep fit by playing football twice a week
I had all my jags but I had resigned myself that sooner or later I would catch this through my job,
I had 2 rough days and there's no doubt in my mind the vaccine really helped me fight this virus, as it's not not the first time I've had a nasty virus,, as for symptoms i had them all mentioned except losing taste and smell... Omicron no doubt
Get vaccinated if you haven't already
