No, doing something constructive is the best thing to do with your free time. Reading just takes atleast a tad of insight/imagination and thought, and literacy, unlike television.
What you say quite literally scares me. Reading is one of the most constructive things you can do. It helps develop you intellectually and verbally. All of the people I've ever known who are good thinkers are also very avid readers. The vast majority of the more intelligent people that I know are also readers. Connection?
