Tools are extensions of the body

Arm-Hammer
Tool Use Is Just a Trick of the Mind — Balter 2008 (128): 2 — ScienceNOW:

Don’t take that hammer for granted. Using tools may seem like second nature, but only a few animals can master the coordination and mental sophistication required. So how did primates learn to use tools in the first place? A new study in monkeys suggests that the brain’s trick is to treat tools as just another body part.

Today must be science day. Here is some evidence to suggest that in order for us to use a tool, our mind has to map it as an extension of our body, verifying McLuhan’s maxim that media are extensions of our nervous system.
