book commercial

I saw a commercial yesterday and i thought it was a fairly descent one. It was sort of a paid political announcement type commercial(not really) and contained an interesting analogy which was pretty much the entire commercial. It simply stated that reading books is like exercise for the mind. In my writing about this, it obviously shows the impact or success of this commercial in getting its point across. If you really think about the analogy or whatever it is called, statement, it really is a clever one. This got me to realize that as much as i keep my body in top shape that i should also be doing that for my brain. I sadly realize that will most likely not happen in the near future because i havn't the motivation for doing so. But hopefully at some time my mind will be adequately exercised by means other than the previous assigned books in school.
