EDIT: I don't mean to be a dick or even argue, I'm just pointing out that these problems do affect people, just maybe not most people through an effective combination of factors that reduces risk (where you live, whether you can afford a filter, etc). I certainly grew up on tap water and I am mildly disturbed people are ok with it causing massive mental health issues.

EDIT 2: Finally, I don't filter water I cook with; I imagine lead would still be a problem there. I probably should filter that water too in Oakland....
