If you want to shave 12-15 years off your lifespan, I suppose the Inuit are a good role model.
From a recent
article:
"The Inuit in Canada's far north have lifespans 12 to 15 years shorter than the average Canadian's, government data showed on Wednesday, putting the aboriginal people on a par with developing countries such as Guatemala and Mongolia."
It doesn't surprise me they get higher rates of diabetes than average Canadians, since diabetes and excess dietary fat go hand-in-hand.
Given their location they may not have many good food choices, but they aren't exactly a thriving people (in many ways).
