I don’t know why, but I have a tendency to learn about things that I don’t think will have any affect on my life.  I recently read an article about road grader blades and how you can make sure that they last for a long time.  It really depends on the  material of blades and it also depends on how often you use them.  Who knows, maybe I will need this information in the future, but I guess I will find out eventually.  I think that this might be something that my brother might be interested in learning about, so I need to show him the article.
