hmm.. this is interesting... the article says "spinal fluid exits the cerebrospinal fluid (csf) flows out of the brain... I wonder where it discharges these waste products. I ask because it is believed we have a sort of chimney on our backs. I think I read this on the article of the Irish lady who could detect alzheimers years before any modern medical detection systems. But maybe it is discharged in the gut? via the mesentery, the new organ they finally named fo rthe stuff that holds our intestines together. If anyone knows where it is discharged, please comment, I'm interested in this, because I do prolong waterfasts every 3 months, and I strongly believe the brain drains waste into my mouth during that time, because the taste in my mouth is godawful, but if there are other exit points the brain discharges waste, we probably need to know about them.

I believe it's discharged basically half directly into the venous system in the neck, the other half goes through the lymphatic/glymphatic system and ultimately also the venous system in the neck. That being said, that's just based on our very crude understandings and I'm sure there are other pathways.
