There was a study[0] connected to videos[1] of particular flashing that trigger plaque-clearing rhythms in the brain.
Maybe placebo but my mind feels quietly clearer after watching. It could be that simply slowing down and clearing my mind for that time would do the same.

Certainly I could not watch this in one, unbroken, session without interruption.
Interesting. Can you describe why? I watched it a few times and wasn’t really impacted by it.
