7. I have long told people that I don't store irrelevant information

I exhibit a kind of incredulity that some people around me remember things I consider worse than useless. And I have an apparently unusual ability to remember vast amounts of technical data and languages. Maybe because my mental memory flushing is so efficient at clearing out the useless information.
I also experience being able to access information I haven’t otherwise thought of in decades especially around languages. For instance, while speaking French with someone recently I came up with several words I have had no reason to use since high school (50+ years ago).
Muscle memory is another method for learning and enables musicians and others to remember astonishing amounts of information to be able to perform without music.
