As someone who has spent time in both I really don't think it's as different as people make it out to be. The only real differences are that cars aren't so common, people have less money, and multigenerational households are more common. But even the small cities are far healthier than rural America from what I've seen of both. They have much more consistent access to health care, mostly ride scooters or walk places encouraging a healthy lifestyle, and are far from starving.
