This is a conversation about the levels of CO2 and how it effects a person, especially their sleep. In this part of the conversation people have started to talk about how the temperature also effects your sleep. This was a natural progression, as less CO2 needs more ventilation, and brings with it colder temperatures.
You then started talking about two groups of indigenous people in different climates. Brilliant, I'm interested in how these two groups of people sleep! You however did not talk about these people's sleeping habits (as would have been another natural progression for the conversation) but instead go completely off the topic of conversation and talk about a bunch of unrelated topics, with very tenuous links between them.
Your comment did not add to the conversation, at all. Neither has mine of course, but I hope it goes some way to explaining the unpopularity what you said.
