Just came to me from an inspirational angel.
What if when in medical documentation and research we expressly write down "environmental factors," we actually mean the "Soul"? If epigenetics were the source equivalent for "curses" [family, personal, hereditary, etc.], this could be regarded as the highest form of open-source spirituality that is compatible with Christianity to date in modern science.
Your soul still absorbs all those feelings emotions and experiences that one person has to go through.
