Yes. I think scientists discovered within the last 10ish years that the brain has a lymphatic system at all. That kindof blew my mind, they they've only just discovered an anatomical feature of the brain? I find that kindof crazy, like, were they even looking?

That sounds bang-on accurate, friend. That also makes the importance of exercise more obvious and subtle to me, walking being most gentle on the body but also requiring at least 30 minutes to really be "exercise". And, then, how good is the air being cycled in on those breaths. I imagine it's damn near impossible to find good air for lots of people who don't have a good tree-filled park close by. I have both seen the morning "green air cloud" hanging over Istanbul on the flight in, as well as the amount of smog on the ground in the morning. Returning to the US the first time visiting Turkiye I was immediately struck by the amount of greenery on the east coast here in the States.
They were, but ... if you don't know what to look for you probably don't find it!
Apparently it's not something you can simply dissect and point at it easily. (Otherwise people would have found it. Though it still happens from time to time that folks find new ligaments here or there in the complicated joints. But AFAIU the brain is much harder to preserve and prepare.)
Thanks, that's interesting. This shows the shallowness of my understanding:

In living things, all the processes seem to mesh so it's plausible that even this fluid movement has some impact on cognition.
