Hey @agmoore2, thanks for your nice reply again. Yes, I think you can fool your brain. In the absence of natural light, you can readjust your clock, as they do it with the flies. Don't ask me how long it takes. Experiments with people in bunkers or caves have shown that they create their own rhythm after a while. For turning night to day and day to night is, therefore, possible, but I don't know whether they already tried it in this fashion.
Thanks also for the feedback about the sleeping mitochondrion. I always try to find a good story to entertain the people at least a bit.
Have nice remaining weekend
Best
Chapper
