I know my brother, and although he carries 0 in health insurance he is one big time Republican conservative. Yes, he goes on the trips, as cheap as he is, he is one of those who thinks he is smarter than everyone else, (he has a point), and he is investing whatever he would sink into health insurance into stocks and bonds I am sure.
Although he has reached that 40 mark he considers himself way younger (think 29). Have you seen this syndrome? The I will never get old so I don't need health insurance syndrome?
I don't have any strong impressions about who has or doesn't have health insurance.
