Exercise Makes You Smarter!
You may have heard the old (and by old I mean ancient) expression: A sound mind in a sound body. Or, as the Romans said, way back in Roman times, Mens sana in corpore sano. Well, according to some recent research findings, it turns out the two really are linked. An article in Health Day states:
People with the highest cardiac output for their body size (cardiac index), meaning those with the greatest blood flow from their heart, tended to have more brain volume, which generally indicates a healthier brain.
In fact, the researchers said that people with the lowest cardiac output showed nearly two more years of brain aging than did those with the highest cardiac output.
