It sid efinitely an interesting topic. As humans, many of us like to believe we have control of our own emotional health and don't believe in environmental influences like windy days contributing to headaches, barometric pressure on migraines, and moon phases on depression and anxiety. I believe in environmental influences, but the academic environment doesn't like to support such notions and don't study it much. It is a pity that our scientific world can be so narrowminded at times.
