This is personally interesting to me, as I am the first generation of my family that is not semi-nomadic (not sure about the exact term in English). When you say you've cured it - did you move somewhere more adequate or you did you stop moving?
Mine are from south-eastern Europe and I have been ignoring the longing for my mountain for so long, I've figured everyone longs for their habitat anyways so it's not that special.
We also have a lot of mental health issues in my family since the switch to "civilization", not sure that any one of us is totally sane.
I think many people are suited just fine to handle all this pollution and stress and stationary living. The farmers have taken over the world and they have left us hunter/gatherers to struggle.
