Which “old brain” or “new brain” themes do you detect in your life, that determine your typical stressors?
Try to describe how your organs adapt to these!
My examples: 
*Old Brain: I have good hearing, but some hyperacusis for distracting noise. That is a function changed in favour of hearing danger for survival. Having been born prematurely and separated from my mother after birth, I never felt safe with other people as a child.
*New Brain: I had a big self-devaluation in my early adulthood regarding the worthiness of my roots and parents. During the life situation, my left (parent-child) ankle deformed which is a minus in function of stability. I had a hard time "taking a stand" for my parents and education.
