It's just a bonus guide, absolutely unrelated to health, and absolutely not important for your health journey, so I made it unlock at a high level, so that you forget about it and don't think about it, and think about your health journey instead.
But if you've been here for a while, and are well versed with all the information we go through here, you might find it very entertaining and tought provoking, even tough you might not be someone to use it practically.
