In an effort to share a Huberman podcast, I found a guy reacting (negatively) to it. And the critic was talking about something called “Active Focus”.
I’m going to leave this link [1] here for you to follow. Since I am just falling down this rabbit hole myself.
But if you do go down this rabbit hole, feel free to share info in this thread…I might also add my email in the bio. Anyways, good luck!
