Have you read the book 'Head strong' by Dave Asprey? It is very similar to your series I believe, also about how these mitochondria play a crucial role in your body and it proposes ways to improve your mental and physical fitness by optimizing these powerhouses.

I did not really like this authors style of writing. He sounds almost like a Guru who has figured out the one and only way to achieve mental and physical fitness and is eager to share this with anyone. I'm also critical about his arguments because he makes some crucial reasoning mistakes. So I'd love to follow your series to read about the actual science behind it!
