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.
Based on a 150-pound person, 30 minutes of moderate-speed walking burns about 160 calories. This figure varies depending on the person's weight and his total speed; a 125-pound person burns about 135 calories in 30 minutes walking 4 mph, whereas a 185-pound person burns about 200 calories.
