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.

Why can't they put the effects of exercise and sleep into a pill, patch, or suppository? In all seriousness that'd be pretty great.

Id just take the sleeping pill, i like to exercise and wouldn't want to lose that, but really don't like sleeping.

How does doing exercise not make you tired? When I do a workout I can’t fight the exhaustion when 9pm hits and I’m in bed and sleep like a rock until the sun comes out.

When you feel sluggish and tired that is a warning sign your body needs exercise. I say this as someone who avoided exercise entirely until my mid-30s. The exhaustion is also a feature. It probably helps one sleep which is when the waste is being flushed from the brain by the lymphatic system. Also, other studies have shown sleeping pills can shut down the nightly waves that drive the cleaning.
