> The idea that watching a video triggers some waste clearing mechanism is pretty wild.

It kind of makes sense. We can look at images of food and get a physical reaction like hunger, or look at macabre images and feel disgust, or stare at animations for one minute and then be affected for many minutes afterwards when we look away.

It doesn't surprise me we're still discovering new mechanisms for triggering physical reactions in our bodies.

Edit: I do agree it's pretty wild regardless :) Especially wild if we're finally discovering mechanisms that have useful effects, not just "fun" effects like visual distortion.

Not wild at all. think of brain cancer (AKA GBM AKA glioblastoms multiforme).

The more you think, the more blood to the brain, the faster the cancer grows.

Think about it.

You can also watch a video that will add waste to your brain.
