Wanna grow old in Michigan? Go NORTH! Or west…your choice
A study from he University of Washington says that the life expectancy in the U.S. is 79.08 years. In Michigan, as a state, it's 78.26. But, according to DailyDetroit.com, when you break Michigan down county by county, somebody born in Leelanau County can expect to live to live until they're 83.1 years - about 8 years longer than somebody born in Wayne County. Ottawa County came in second at 81.45 years. So, move to "The Dunes", or move to Holland.
Nationally, according to the Washington Post, the longest life expectancy occurs in three counties in Colorado, near Aspen, Colorado. One of those - Pitkin County, has the 7th highest pr capita income of any county in America. So, you may also choose to move to the Rocky Mountains, but, we'll miss you and you'll be broke.
BTW - from the map of all the counties in the U.S., it looks like Clinton County is the best place around here for maximum, "get off my lawn!" time.
