To be fair, things like alcohol abuse are major problems among Inuit communities these days (not to mention murder and suicide. Living in the northern Territories is pretty much the worst place to live statistically in this country). They've also got the same sort of problems as many other native communities these days. Ready access to tobacco and troutty modern food compared to their ancestors, combined with all of the usual social problems that have developed purely as a result of our treatment of them since white people first landed on their shores. I'd take any stats about their life expectancy these days with a grain of salt since I can pretty much guarantee that the numbers living their traditional life style with their traditional diet would be few and far between.
