Memory must be everything. Have a recollection of what happened yesterday in order not to repeat yesterday mistakes. Nothing is new under the rainbow, so remembering what happened 40 years ago must be a doodle.

As an example, in which order did you buy these vinyl records by Spirit? Did you buy the first one first, or the second and third one first. And if you don't remember how come you don't remember simple things like buying vinyl records 40 years ago? And in which order?
