I am younger than you, but I agree that there does seem to be a point where as people "age out" of DREAM, they are finally at an old enough age where they can survive and adapt to the country of their birth, even if it seems wholly different. After enough time passes, the "I've been here too long to adapt to somewhere else" rationale morphs into a conscious choice to remain here in spite of its tortures that you willingly subject yourself to.
