I have thoughts about a WoB on oxygen levels on Roshar that's worrying me a little.
Roshar has high oxygen level. Okay, we knew that. Rock often calls others people "air-sick lowlanders" and it's just a joke about how strange other people are. Right?
But then, throw in the bit about high oxygen level doing "weird things to people as well" and I start to wonder, maybe "air-sickness" is real. Maybe the oxygen-rich air is hurting people's health (physical or mental) somehow. Maybe Unkalaki observed this and they know that thin mountain air is better for health, long-term.
