Is Mid-Life the 'Prime of Life'?

We know that different cultures, and different time frames, posit human development differently. For example, the concept of childhood did not fully emerge until the eighteenth century, but in our current culture a quasi-stage of 'extended adolescence' has evolved to recognize that many people do not take on adult responsibilities until some time in their thirties.
The concept of 'middle-aged crisis' so common in America would be quite foreign in a culture that does not even have a concept of 'middle age' (Shweder, 1998)
NUMBER THE QUESTIONS IN YOUR POST. You do NOT have to repeat the actual question, just number your answers to the questions. It will help you to organize your writing.

1. In America, given the latitude about when a person would be 'established' or 'accomplished', at what age do you believe people achieve 'middle age'? Is it 30, 35, 40, 45 or beyond? Which people? What accomplishments? Do these trends apply equally to persons of different socio-economic status?
2. What historical trends could you document that might be responsible for pushing the age of adulthood in American society later into the life cycle? Are they likely to continue or to change?
3. Do you believe that you have achieved 'mid-life'? Is mid-life the 'prime of life'? What is your relationship to your own 'prime of life'?

Show evidence of thoroughly reading and listening to the course resources. This is preferable to outside research. But if you provide additional resources, they will be graded on their scholarly credibility; that means sources of questionable truth may result in a lower grade on the post and sources of good credibility may result in a higher grade.
