The gateway to a new turning can be obvious and dramatic (like the 1929 Stock Market Crash) or subtle and gradual (like 1984's Morning in America). It usually occurs two to five years after a new generation of children starts being born. The tight link between turning gateways and generational boundaries enables each archetype to fill an entire phase-of-life just as the mood of an old turning grows stale and feels ripe for replacement with something new.
