Any Sky thoughts?
Bro I ALWAYS have Sky thoughts.
Today's thought: Sky was the second person from Skyloft in-game who made it down to the Surface. Zelda had the help and guidance of surface-dweller Impa as she adjusted to the change in altitude, air pressure, etc. When Groose joined them on the Surface, he remained at the Sealed Grounds, likely exerting himself but not to the aerobic level that Sky was. And, to be fair, Groose also had an Impa to look out for him while he adjusted.
Sky did not. Sky kept pushing himself like crazy come hell or high water, never stopping, barely resting, and running himself into the ground until the very end of his journey.
When you move from an area of low altitude to high altitude, you run the risk of altitude sickness because O2 levels are much lower and your body works harder to transport oxygen. When you move from an area of higher altitude to lower, though, the opposite can happen. Your cardiovascular system is so hyped about the extra O2 pumping through your veins that you might overdo it. And I get the feeling that he reaaaally overdid it.
So maybe some of that exhaustion isn't only due to all of our cardiovascular and pulmonary headcanons for the poor kid. Maybe some of it was that he was literally just running the rest of his body until things started to break down on him.
