Notes on the book: Spark:

In order for man to suceed in life, God provided him with two means, education and physical activity. Not Separately, one for the soul and one for the mind, but the two together. With these two means, man can attain perfection.


Introduction: Making the Connection

> The reason exercise feels good is blood pumping makes the brain function at it's best building lungs and heart muscle is a side benefit.

> Dr Ratey says the point of exercise is to build and condition the brain.

> We are engineered to move and biological imperative to move is rooted in the area that governs movement.

the relationship btwn Fo0d,physical activity and learning is hardwired into the brains circuitry.

Inactivity shrinks brain while Activity grows brain .

Exercise cues the building blocks or learning in the brain, how it affects mood, anxiety and attention, How it guards against stress and reverses some of the aging in the brain. This is measured in lab rats and identified in people.

Exercise increases levels of serotonin, norepinephrine and dopomine- important neurotransmitter that traffic in thoughts and emotions . Toxic levels of stress erode the connections between billions of nerve cell connections & cronic depression reduces the brain size.

>Neurons in the brain connect to others through leaves on a treelike branches and exercizes cause those branches to grow and bloom with new buds.

Muscles produce proteins that travel through blood steams to the brain.
