The next question I have is do they try to regulate your health..ie do smokers or obese pay a higher premium ? Obese is a diagnosis given to anyone in America that there BMI (base mnass index calculated based on height/weight proportions) is 25% above normal.
Is everyone insured equally regardless of lifestyle choices?.
National Insurance pays for your healthcare, but the main part pays for your state pension for when you retire ... It is not calculated on your health or lifestyle
