I've had Covid at least three times. It has never been severe; just an intermittent headache.

I wonder if these Covid infections have ramped up my immune system to new heights. I used to get a sore throat or maybe a cold on flights, and now I don't.

I haven't had a cold since Covid began, although much of that is probably attributable to lockdowns, distancing, masks, and driving instead of taking mass transit.

To my knowledge, I have not yet had covid even once. But since Feb. 2020, I also haven't had so much as a cold or the sniffles either, so I suspect that I truly haven't had covid yet.

I attribute it to a combination of masking, my overall lifestyle (rarely on public transport, avoid crowded restaurants etc.), and a good dose of luck. Well, that and I have been doing all the vaccinations (scheduled for current covid and flu vax this weekend).

We'll see how long this can continue...
