I've had Covid twice.

Your experience of the virus is different from both of mine Troodee. I had something akin to a mild flu / heavy cold the second time but no noticeable symptoms at all the first time. I've had flu twice in my life and those were nowhere near a flu in my case and I've also had worse colds which have left me with more significant short / mid term after effects.

I'm a fairly fit and healthy 59 year old male with no underlying health conditions. Maybe it affects other less fit and less healthy people with certain underlying health conditions slightly differently? But then the same can be said for a cold or flu virus.

Completely wrong of you to assume it'll affect everyone who catches it the same. Appreciate you're not preaching but neither should you assume.
