How are life course changes timed? (2 ways: f&c) Social constructions of the life course include ways to define when people move from one life stage or role to another. Ex: kung defined as old when they cannot do a full day of gathering a way of defining when to move along . Ex: toddler- toddles along this is a social/cultural definition. C hronological age us in modern societies tied to chronological age by state legislation. = age by the calendar, not by behaviour, ability, etc. Both have implications for both individuals and their societies. There may be conflict over timing: not the time to marry argument. Whole age groups may come into conflict. Transitions are predictable- you can engage in forward life planning, know you will need to figure out where you want to go to university. This can be to your benefit because you know what will happen.
