"Your left brain is a scientist," the doctor says. "Your right brain is an artist."
He says people live their lives out of the left half of their brains. It’s only when someone is in extreme pain, or upset or sick, that their subconscious can slip into their conscious. When someone’s injured or sick or mourning or depressed, the right brain can take over for a flash, just an instant, and give them access to divine inspiration.
A flash of inspiration. A moment of insight.
