I mean, a liter is very close to a quart, so it’s not like we’d be asking people to adjust their mindset completely. And ditching US measures means we could finally, once and for all, dispense with the nonsense of having a dry and a wet “cup” measure.
As for converting records, well, it would be trivial to display a converted value in whatever EMR system a practice uses while noting the values are converted and allowing display of the uncoverted data for validation. (Which brings us to the EMR discussion.)
I am similarly cis gender, straight male (much to my more fluid spouse’s amusement and dismay). I’ve just found the fem- voice actors to be better. Femshep, the female lead in Ghost Recon Wildlands, etc. Or maybe it’s that the brah actors for the male characters sound so consistently dumb. And now it’s just a thing I do.
PS. I hope you love yourself.
