Read a novel.
From a piece in the Los Angeles Times...
We all know that reading a novel can transport you, delight you and intrigue you while you’re reading it. Now, thanks research by scientists at Emory University, we know that immersing yourself in a novel causes measurable physical changes in the brain that can be detected up to five days after the reader closes the book.
The Emory researchers, in a paper for the journal Brain Connectivity, compared the effect to muscle memory.
