Healthcare is its own issue in the US, as I think the general populous is on average a good bit unhealthier than the average Norwegian, for example. I think it's a combination of poor health education (which also goes back to spending) and culture.
- cities designed around cars
- bad worker protection laws
- corporate welfare first before human welfare
- monopolies driving up prices.
Walking is obviously better than not walking, but something other than cars is to blame for the ballooning of the American public. 75% of America is either overweight or obese right now. That alone puts you at risk for about a million health issues and diseases.
Do you have a citation for that? I'm seeing numbers closer to 30% (which is still bad).
"Percent of adults aged 20 and over with overweight, including obesity: 73.6%"
Of course that also shows how many Americans are overweight since the scrawny track kid is considered super skinny.
