Caribou make the longest annual land migration of any animal, with some herds covering close to 1,500 miles a year, almost entirely on foot.
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.
