25. It's a good thing that people forget

Summary of Chapter 25:

- Forgetting things is not a flaw, but it's a way your mind filters out unnecessary information.

- Hermann Ebbinghaus (1886) created a formula showing the degradation of memory. R is memory retention, S is the relative strength of memory, and T is the time which is called the Forgetting Curve which shows we forget information unless it is stored in long-term memory.
