Just a thought about this. I wonder if the improved creative thinking has anything to do with increased heart bpm and blood flow to the brain that is stimulated by walking or other exercise. I noticed the article said "creative juices continued to flow even when a person sat back down shortly after a walk." Perhaps this could be because after a short while a person's heart rate will go back to resting bpm, and the brain blood flow will return to resting state levels. No hard evidence on my part to back this up, just a thought.

You're probably on to an interesting idea. Another topic to google for is blood sugar and insulin levels immediately after exercising.

I once worked with a type-2 and a type-1 diabetic (not the same guy obviously) and as you'd expect with a control loop malfunction illness, both predictable and unpredictable effects were in play.

If I recall correctly the type-2 guy complained that his innards would release lots of glucose while exercising and continue shortly after but his insulin production (or response?) was not so good, so his blood sugar measurably spiked high after exercise while the type-1 had his drop unless he adjusted his dosages. Or perhaps it was the other way around wrt the type 1 guy and the type 2 guy.

Being a spectrum disease, I suspect even a "healthy" individual might have some peculiar short term changes to blood sugar and/or insulin levels.
