Well thought out. Every day our mind processes a huge amount of information. Sometimes it is too much :) It would be nice to have a couple of sentries that would follow the information that our brain consumes. That is, they would play the role of "antivirus" which filters information garbage. I think that in the information age, we must pay attention to the "purity" of our brain. Rid yourself of television and other information garbage. Read proven resources and spend more time relaxing in nature, well, the main thing is to have a positive attitude. I think this will help keep the brain in good shape.
I think that there is a lot of knowledge that is not available to the general public. Nevertheless, thanks to the Internet, our possibilities have expanded.
I've been in these tunnels a couple of times. These were the passages between the old churches. The atmosphere there has a favorable effect on our thoughts.
Thank you for sharing, I really liked it!
