Good question. I was chatting with a friend the other day about the evolution of the human pineal gland. Not only did it shrink over time but it has become overly calcified. If you go down the rabbit hole and dig deeper into this topic, you discover a strong linkage between hormones and the size of the pineal gland. The hormonal disbalances children face today (due to food for example) are a direct reflection of their behavior. There's tremendous power in that small pine cone-shaped "nugget" or grain of rice. The smaller it gets and the less we use it, the stupider we become as a species.
I'll go with haiku 6 as it reminds me of past generations; our ancestors.
I’ve never heard of a linkage between the pineal gland and hormones before. Interesting. That could explain a lot of what I’m seeing in schools these days.
