I like the comparative you drew between reading and working out at the gym, seeing as to how the brain is also a muscle that needs to be trained on a daily basis to keep it performing on all cylinders. 

I've only recently started reading printed materials again, and this piece does resonate well with me. My current read is Russell Brand's Revolution. Do give it a try, I find it very entertaining as I'm a fan of his stand-up, and his style of writing complements his stage persona too. Keep up the writing!
