Memory Craft: Improve your memory using the most powerful methods from around the world by Lynne Kelly

5.0

I think I'm now inspired to use memory palaces to learn the sum of human knowledge plus a couple of fun card tricks.

This book is basically saying certain indigenous cultures had tools, imagine a block of wood with different things like shells/beads/rocks stuck to it, that served as a "hard drive" of their entire cultures history and knowledge.

That's the kind of ultra fascinating theory I have a lot of time for.
