Things aren't too good in New Zealand either. Over half of people in this country are overweight, and obesity is a major problem among Maori and Pacific Islanders (who combined together constitute about 16% of the population). The Europeans (white) tend to be slightly overweight.
One of your recent favorite sons, Peter Jackson, seems to have lost a ton of weight. Good for him. Also, you guys need to eat big portions to keep those elite rugby players in top form.
Interesting. I was just on the South Island and saw little of that. The only country i've been in where I observed lots of large people was Scotland. And even then they didn't have as many as us and they lacked the truly giant class.
