> "And if humans could see magnetic lines, we'd all certainly be better matched to our earth environment, so does that mean all humans disabled?" In the sense of being fully aware of our environment then yes, all humans are disabled in that regard. Furthermore, disability is not a binary categorisation where you're either disabled or you're not, it's a scale, but crucially it's a scale based on your abilities to engage in the world around you and inside of you. We only use typical human behavior as a measuring point so that we can categorise people in a binary fashion. In other words, you can look at disability through the lens of human society in order to class a person as disabled, but disability can be thought of in much more general terms, which is where the WHO definition comes in.
