Some people are afraid of learning or trying new things. At my new job I am learning about the blueprint industry as well as digital scanning and archiving of paper and microfiche documents. The head reels at how much information I know and do not know about this, but I will master it. I'm just surprised at how much there is. Anyway, you have to change with the times. I don't mind the older formats, but in technology, you have to embrace new things. Same thing with your job, or otherwise you become obsolete. I think that is a contributor to Alzheimer's and other diseases of the brain. So keep excercising your brain as much as your other parts of your body.
