We take the idea of use it or lose it to mean we need to keep our brains active or risk a decline in our thinking powers
However a new study on 700 Scottish people in their 70’s found exercise was more important for brain health than intellectual stimulation or even social engagement.

The study used brain scans and questionnaires.
