If I weren't so tired today I might take a look at the articles. Thank you for posting them.

I believe in the heritability of mental illness - - at least in some cases - - because it occurred on my dad's side of the family: my dad's mother had bipolar disorder. She was in and out of psych wards her entire life, one likely reason being she refused to take medication. She was given nutrition/hydration through an IV because she refused to eat or drink. Her mother committed suicide.

Nature or nuture? Maybe a little of both? In some families there's a clear pattern and that includes mine. It makes me a little concerned about my young nieces. Will they luck out or not . . .
