Quite a few of my good friends are memorization machines. Some of them are able to quote religious scriptures, poetry, and various historical writings, others can quote scenes from movies, songs, or plays verbatim, and some can recall times we've hung out from start to finish, from what was discussed to what was done. I don't really think any of them have developed these abilities through formal schooling or techniques, but just by being very passionate about the things that they find interesting or valuable. I wonder if memorization was taught and developed less by emphasizing exercise and practice, and developed more by emphasizing what people are passionate about on personal, individual levels, more people would develop memorization skills.
