I’ve just watched a documentary called Three Identical Strangers, about triplets separated at birth who found each other at the age of 19 years old.
I had no idea where the documentary was going, but it delved into nature vs nurture, and twins and triplets whose biological parents had some mental health issues, and their children studied years after. I should mention the kids were placed in completely different households – blue collar, middle income, affluent – not even knowing they had identical siblings, all within a hundred mile radius. A set of female twins were in the documentary a bit as well.
Bipolar and Schizophrenia were discussed (surprise), as well as suicide, all supposedly in the name of discovering, what is truly hereditary, what do we decide for ourselves, and – what I wonder and read about quite a bit – nature vs nurture.
You might want to check it out, but please know it’s emotional.
