Understanding the risks you face in retirement is a great place to start when beginning to plan for retirement. As equations go, it's a simple one: There's risk and there's return. Unfortunately, human nature being what it is, people tend to focus on one side of the equation to the exclusion of the other. Prior to the market crash in 2008, many retirees and would-be retirees -- despite warnings from countless pundits, academicians and the like -- focused mostly, if not solely, on return. Now, however, the pendulum has swung in the complete and opposite direction and everyone is talking about the risks associated with retirement.
