Here's a list of states from first to last that are the best to retire in. http://www.money-rates.com/research-center/best-states-for-retirement/2012-complete-list.htm
The criteria used in determining the rankings were:
Cost of living
Violent crime rates
Property tax rates
Life expectancy for seniors
Recent population growth in the senior demographic
Unfortunately, Ohio ranks 44th, but that's not as bad as Michigan's dead last position.
