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.

Lymph circulates way faster when exercising, so there's that. Like 3x increase. IDK if that translates to brain lymph, because other lymph vessels are much closer to working muscles. But lymph in general circulates in conjunction with skeletal muscles and all lymph vessels are systemically connected.
