This is what I did today. I really struggled with it but it was fun. When I quit, I had a hard time figuring out how to get the hook started again.
It's amazing to watch some of the grandma's I see in the ER. They go like wildfire and barely give it a thought while I struggle with each single loop or movement.
I guess it's about cultivating or "burning-in" distinct neural pathways, and in some surprising ways, is a little bit like yoga.
