Elasticity comes from the Greek word "propulsion." Elasticity is our basic animal drive that powers our muscles and gives us strength and balance, mobility, flexibility, and grace.
Plasticity is derived from the Greek word meaning "formed." Plasticity is the tendency of the brain to shape itself according to experience. Plasticity is the basic mental drive that networks your brain, giving you cognition and memory. The brain has a lifelong ability to reorganize neural pathways based on new experiences.
Throughout your life, your neural and muscular systems reorganize and reconstruct themselves in response to new stimuli and learning experiences. This body-mind interaction - it's elacticity and plasticity - is what stimulates brain cells to grow and connect with each other in complex ways.
Train your brain and Get Strong.

He hadn't slept in fifty-seven hours and he was struggling from the brain-altering effects of oxygen depletion .He turned to begin the perilous descent from 29,028 feet, twenty other climbers were still pushing doggedly to the top, unaware that the sky was filling with clouds.... "This is the terrifying story of what really happened that fateful day at the top of the world, during what would be the deadliest season in the history of Everest. In this harrowing yet breathtaking narrative, Krakauer takes the reader along with his ill-fated expedition, step by precarious step, from Katmandu to the mountain's pinnacle where, plagued by a combination of hubris, greed, poor judgment, and plain bad luck, they would fall prey to the mountain's unpredictable fury."
