You Do Not Use Only 10% of Your Brain
Kwik rejects the popular claim that humans use only ten percent of the brain. His analogy is that people use their bodies but achieve different performance depending on how well they train strength, endurance, flexibility, and agility.
- People use the whole brain, but not with equal training or efficiency.
- Mental capability can weaken through disuse, much like a muscle in a sling.
- Reading speed, focus, understanding, and retention reflect mental fitness.
“The truth is that we actually use 100% of our brain.”
“it's use it or lose it.”
