To be fair we have well defined equations to decide if a sample size is large enough and to calculate the error in our errors. In the case your examples, we already know that the CFR is lower than 10%, so a sample of 10 definitely is nowhere near enough to tell us anything useful. Now if the CFR was 50% and you had 0/10, maybe it'd be worth looking into it. I'm curious though, have any of your friends had longer term effects? longer term smell/taste loss, brain fog, heart issues, memory issues, breathing issues, etc? The early reports on long term impact are at ~10-20%, so you may have 1 or 2 in your sample, but again your sample is small enough that you very easily could've had 0 too. Again, it depends heavily on what you're trying to disprove and what the rate of it is.
