Signed in 1840, the Treaty of Waitangi is an agreement between the British Crown and Maori. Around this time, there were 125,000 Maori and about 2000 settlers in New Zealand. Sealers and whalers were the first Europeans settlers, followed by missionaries.
Their male subjects burned 105 calories running, 52 walking; the women, 91 and 43. That is, running burns twice as many net calories per mile as walking. And since you can run two miles in the time it takes to walk one mile, running burns four times as many net calories per hour as walking.
Similarly, a 155-pound person walking 4.5 mph burns 186 calories in 30 minutes. This means that the average man burns about 194 calories, while the average woman burns about 178. Men burn more calories because they have more muscle, but they also need more calories for the same reason.
