## Summary

Pooling data from eight studies covering over 33,000 people, researchers found that higher physical activity in midlife was linked to modestly better memory, mental processing speed, and overall thinking ability later in life. The effects were small but consistent across multiple cognitive domains. However, the results for executive function and verbal fluency weren't meaningful. Almost all studies relied on self-reported exercise, and only one looked at men and women separately.

## Practical Takeaway

This study suggests midlife physical activity is associated with better cognitive function in later years.
