I asked this in Medical: I wonder specifically the effects on the brain of chronic low-level exposure to carbon monoxide due to indoor use of gas flames for lighting and wood/coal fires for heat, not to mention particulates from such flames. We hear of the Flynn Effect (a very significant increase in performance on IQ tests) which I have read is attributed to nutrition but perhaps people have thoughts about indoor heating/lighting by local combustion's contribution to nervous system issues.

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions on social sciences other than History are off-topic here, unless they also involve history in some fashion. While ethics, archaeology, etc. are all connected to history, each field has their own experts who are better equipped to answer such questions." – Pieter Geerkens, Jos, Danila Smirnov, Brasidas, José Carlos Santos
