The explanations in the previous chapter show how much the individual stages of the life-course have shifted and changed in their extent and form over the past 100 years. Some of the challenges resulting from this restructuring of the life course for the biographic organisation and socialisation have already been mentioned. Today, a very open form of the life course is predominant, which enables a 'chosen biography' but also requires a demanding 'biography management'. As has been shown, the implementation of such a biography management often fails today due to a lack of personal competences, but also due to persisting traditional, social, legal and institutional regulations stemming from the era of the alleged standard biography.
