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.

Adequate sleep and exercise are two good ways to improve lymphatic drainage.

What's the mechanism for exercise helping that? I understand sleep, but what does exercise do?

Pressure from contracting muscles and increased extra cellular fluid exert pressure on lymph vessels and increase flow of lymph fluid.

Exercising in water can exert additional pressure.

Thanks, I have some reading to do!
