> Unlike the U.S., similarly large and wealthy nations have long had universal or near-universal health coverage and more robust access to health care. Although the U.S. has recently reached an all-time high rate of insurance coverage, it still lags behind its peers and the ongoing disenrollments from Medicaid may cause the uninsured rate to rise. Additionally, even people who are insured in the U.S. often face such high out-of-pocket costs for medical care that they go without needed care or incur medical debt. Future policymaking in the U.S. may continue to focus on improving insurance coverage rates and addressing cost-related and other barriers to care.

But one can very easily argue that American health outcomes are significantly driven by the average number of steps they take per day relative to other geographic peers.

Astonishingly few Americans are getting more than 15 minutes of light aerobic exercise in per day. And that exercise is largely being spent moving between seats.
