I'm not sure if this is the same in thought as your is, but in regard to us, but I do think that some mature, age, gain experience and/or grow up dependant on how much they present to experience life and are conscious of everyday living.

As they gain these life experiences and learn additional coping skills, the switching process seems to slow down.

Being that we just hit a flip side of ourselves, a whole new us, we are having to start over which can explain the constant switching again.
