I saw my doc last week to get a referral to a surgeon to remove a growth on my face. (No, it doesn't hurt, and it's most unlikely to be cancer but let's not take a chances.)
She looked me over and asked, "Are you still on that keto diet?" I said, "Sorta -- with a bit of a net carb boost to accommodate enough milk to deal with that osteopaenia you warned me about." She pages through a bunch of lab results on her computer. "Why do you have absolutely perfect blood lipid levels?" "I dunno. Just lucky I guess."
This may be the first time in my life I've ever been perfect at anything.
