adhd is a personality trait that's within the normal range of human experience. the traits are real, its just not caused by any pathology.   > they just refuse to grow up. its more that for whatever reason peoples' endocrine systems are so fucked that they can't grow up, they never finish puberty. a lot of people think its plastics or other chemical xenoestrogens or whatever, but i disagree; our environment was more polluted over the last century, it's getting cleaner. 70 years ago people were surrounded by plastics and lead and their endocrine systems were fine. if it has an environmental cause it could only be through second-order genetic effects.
