Bright side for those of us with the ACE alleles that make for higher blood pressure and increased insulin resistance in response to saturated fats is that we are less susceptible to Covid-19.

Also, given that these were studies done with lab mice (multi-generationally inbred to the point of being almost-clones genetically). I find the variability surprising. I'd also be surprised if there were large differences in their microbiomes, considering the very similar environments they've been raised in.
