My grandfather (doctor) always told us, only babies need milk, and what they need is human mothers milk. Other than ice cream, I don’t drink the stuff, yuk.
I’ve always subscribed to your grandfather’s point of view. I stopped drinking milk when I was 5 (I’m now 60) but still eat other dairy products. Milk is for baby cows who need to build the fat. To me it has always tasted like crap.
