Humans learn automatically.
Learning makes use of audio, visual, touch, taste, and smell functions to provide an interpretation of truth. Visual elements added to videos are entertainment.
Reading focuses strictly on learning with occasional imagery, watching TV focuses on both audio and visual elements. Reading is true creation as you’re required to build your own imagery.
Reading is the process of silently talking. You are able to learn on a deeper level because it requires all of your thinking energy to interpret words. You’re putting a restraint on other senses so that you can only focus on the interpretation of what you’re reading.
