Did You Know?
A large 2017 smartphone study across 46 countries (published in Nature) found average daily step counts varying enormously by country, roughly 4,000 to nearly 6,900. The researchers found that inequality in step counts within a country predicted obesity rates better than the average did.
George Meegan's 1977-1983 trek from the southern tip of South America to Alaska covered roughly 19,000 miles on foot the entire way, still recognized as the longest unbroken walking journey ever recorded.
