If you'd like to get specific, reading is a good habit for many reasons. Reading regularly will increase your vocabulary and comprehension of read subjects. Also, the more you read, you will find that over time the speed at which you read will increase. Reading also keeps your brain healthy. I am not a doctor, but unlike television where images are provided with the content, reading causes your brain to 'think' and visualize the subject of which you are reading and in turn creates new pathways in your brain. This will help you understand new concepts quicker and recall knowledge you already posses faster.
