Post random knowledge you acquired while researching for your works. We all have our areas of expertise; those don't count. Bonus points if you can guess what someone else is writing, based on his research.
I'll start:
>Cluster-headaches are linked to the hypothalamus, and they are among the worst pains known to mankind, feeling like someone is pushing white-glowing iron into your eye
>Damage to the supramarginal gyrus in the temporal lobe can cause Gerstmann-syndrome, meaning that you can't read, calculate, count, or even into left and right
Pic unrelated, it's from my old info-folder.
