C'mon. The comment you're replying to with "makes sense" is about city living vs rural. You weren't commenting that it's unknowable. You stated that "unnatural lights" and "disrupting biological rhythm" (whatever that means) probably cause one's brain to go "haywire" (implication being: and commit suicide).

As if there aren't uncountable other variables that have changed dramatically over millions of years. Or hell, do you even know if suicide rates are higher today than they were millions of years ago? No. You came here to try to suggest city living was inferior to rural living, and used "millions of years of evolution", and some implication that modern rural life is somehow more similar to those millions of years than urban life.
