How do we clean out our brain of waste? 

Edit: Just says they boosted the lymphatic system of the mice, doesn't say how. If you give "strengthen lymphatic system" a Goog you get physical exercise, hydration and healthy diet.

Not sure specifically related to this article- but there are lymph nodes in your neck and armpits. Massaging these areas regularly apparently improves circulation- but I’m sure there is more written out there than this; also not sure if applies to brain lymphatic system.

Instructions unclear. I'm massaging my armpits now to see if I can understand further.

Damn it! I'm massaging my armpits and I can't remember why!
