Explained in their brilliant concise fashion, the team of AsapSCIENCE put together this neat online demonstration of the effects of the decay of your inner ear. While other organs can repair themselves over time, the cells in the inner ear just... well, they die.

Grab some headphones and give the video a watch to see how your inner ear health is getting on.
