Ask Lemmy

If memory is so important to you than you really need to stop reading and writing. Before literacy was common everyone remembered everything. Knowledge was oral. People had fantastic memories because they had to.

"Report says that in the schools of the Druids they learn by heart a great number of verses, and therefore some persons remain twenty years under training. And they do not think it proper to commit these utterances to writing, although in almost all other matters, and in their public and private accounts, they make use of Greek letters. I believe that they have adopted the practice for two reasons — that they do not wish the rule to become common property, nor those who learn the rule to rely on writing and so neglect the cultivation of the memory; and, in fact, it does usually happen that the assistance of writing tends to relax the diligence of the student and the action of the memory."

Now my mind is filled with knowledge of current ly useful processes instead of facts that aren't immediately useful. I know details of cooking, 3D printing, programming and home repair. Your brain is finite. It's why your memories are deleted when you sleep.
