IF ID WAS MEDICINE
I could tell you you were sick, because you *look* sick. We’d have some fantastic metric for sickness that no-one has ever used and our “sick or healthy” filter would just be a concept…. that didn’t work. I could maybe tell you you were sick, because you look sick but could make no comment about the disease causing the sickness, how it makes you sick or how to cure you. Real medicine would be a dogmatic religious belief, though.
Everyone can play! Pick your own analogy!
