Marshall McLuhan[i] was right. A new study published in the journal Cell Biology provides the first direct proof of a longheld notion among technologists: tools fundamentally alter the way we perceive our own bodies.
"To be accurate in doing an action with a tool, you need to make the tool become a part of your body," lead researchers Lucilla Cardinali and Claude Bernard told The Scientist.
The implications of this idea are staggering, and it is something every high school student needs to learn. Using tools intelligently and appropriately is essential to a balanced and successful life. That begins with an understanding of our relationship with tools and how they alter our way of seeing the world.
