Start running and watch your brain grow, say scientists

The health benefits of a regular run have long been known, but scientists have never understood the curious ability of exercise to boost brain power.

Now researchers think they have the answer. Neuroscientists at Cambridge University have shown that running stimulates the brain to grow fresh grey matter and it has a big impact on mental ability.

A few days of running led to the growth of hundreds of thousands of new brain cells that improved the ability to recall memories without confusing them, a skill that is crucial for learning and other cognitive tasks, researchers said.
