Surprise. They are already doing this in America.
I know Insurance companies are doing it....In order for us to get some kind of piddly credit ($50?)...my husband made me fill out a Blue Cross health questionnaire several years ago. They wanted to know drinking habits, waist size, weight, etc. I got a letter back telling my my BMI was too high (I’ve always been heavier, because I HAVE more MUSCLE mass than the average woman). And, they also said I drank too much wine...(I think I told them 1 glass of red a day....) I have exercised ALL my life and am in better shape than most women half my age.
