Repeated subjects

I can search my 6000 blog posts for a word or phrase.  As I get older, a subject pops up, some subject of interest. That can happen repeatedly without my remembering that I have written in my blog about it before. So, yes, I can state that X is of interest when I have stated that interest previously.  

I made a note that I might want to state that I read that people who have a job of testing ballpoint pens to see that the pens write properly often use the name “Eisenhower”to get a new ballpoint working properly.  You know how it is: you don’t want to put a big dent in the ink supply just to test the pen.  I read that in my granddaughter's beloved cursive style of writing, the 34th president’s name has handy dips and curves that tend to get a ballpoint working nicely.

But since I have found repeated subjects before, I searched “Eisenhower” and found at least two posts that made the pen-testing point.  As Whitman nearly said, I repeat myself?  So, I repeat myself. Teachers are used to repetition.
