Hello Ara,

You used a key word in your post. Metabolism. I am suggesting a study at the molecular level. I agree that we could film animals over a long period of time, and see if they are pacing, or acting differently. That is one approach. But what about how much they are eating? How about the the other end of the alimentary canal, fecal matter? There are many different ways to study it. Ara, what animal behavior would you look for? I know the Chinese have done work on this. They evacuated an entire city because worms were crawling out of the ground in winter... Hmmm Just asking.
