Your brain becomes fossilized with age.

In order to be classified as a fossil, a specimen usually has to be over 10,000 years old. When you consider this, comparing aged brains to fossils isn’t exactly a flattering metaphor. Fossils are hard, lifeless remains of what once was a thriving being – and that’s exactly what your brain becomes with time.
But it starts even earlier than that.
