We spoke about stages..Erickson says so much.
People who work as your SO and you also will have fine tuned skills with the young.EG a maturity other people may not have yet developed.

Stage 7. Middle Adulthood: 35 to 65

Ego Development Outcome: Generativity vs. Self absorption or Stagnation

Basic Strengths: Production and Care

Now work is most crucial. Erikson observed that middle-age is when we tend to be occupied with creative and meaningful work and with issues surrounding our family. Also, middle adulthood is when we can expect to "be in charge," the role we've longer envied.

The significant task is to perpetuate culture and transmit values of the culture through the family (taming the kids) and working to establish a stable environment. Strength comes through care of others and production of something that contributes to the betterment of society, which Erikson calls generativity, so when we're in this stage we often fear inactivity and meaninglessness.

As our children leave home, or our relationships or goals change, we may be faced with major life changes—the mid-life crisis—and struggle with finding new meanings and purposes. If we don't get through this stage successfully, we can become self-absorbed and stagnate.

Significant relationships are within the workplace, the community and the family.
