I can certainly speak somewhat to that, not to the in-depth research, but the document we have there is something that is quite new in the industry. The simple relationship is that what's good for your body is good for your brain.
That happens because the neuroplasticity in your brain helps you to learn better and retain better. You can learn new things. Just because we get older, it doesn't mean we can't learn new things. That's so very important for older adults because of the obvious concern with Alzheimer's and dementia. If people are able to stay physically active and challenge their brain at the same time, they will be able to improve and maintain their mental capacity, their memory, and also ward off mental illness and Alzheimer's. There is a definite link between physical activity and mental health.
