When I find something interesting in a magazine, I tear it out, put it in a folder, and file it away for future reference, stuck in one of many bookcases. I then forget where I put it, and even forget that I ever saw it. I find it, years or decades later. Sometimes it is still interesting, and I put it back where it was and forget it again. Sometimes it no longer has relevance, and I throw it out.
This is not age-related. I have been doing it my entire life. It is not senility. It is a cultural trait. Somewhere on earth, I feel, there must be others who behave this way. I hope I can find them someday, and enjoy being one with my own people at last.
