Do people regularly claim on insurance for NHS doctor's appointments? I know I never have. Regarding the smoking etc, I'm pretty sure that health insurance companies ask if you smoke (and yes, double the cost if you say yes), and giving a lying counts as insurance fraud. Due to that, I'm not too sure how relevant the NHS records would be, other than in cases where someone has lied, in which case I'm not too inclined to feel sorry for them.
