When I read that Eric Hoffer believed life unfolded in stages of thirteen years my first reaction was, "Not way." We're all different, each life is a journey original.

Since I am an engineer by education and persona – both model addicted and terminally analytical – I had to conduct a self-test on the hypothesis.

 What a surprise to find my life had unfolded as Hoffer proposed... nearly. 

End Note: I do not believe this model holds for all, but am convinced each life is a progression of segues and stages, all flowing from change, chance and choice.
