Sounds like making sure you are cardiovascularily fit leads to healthy brain aging. Whatever that means.

The literature examining the relationship between cardiorespiratory
fitness and the brain in older adults has increased rapidly, with 30 of
34 studies published since 2008. Here we review cross-sectional and
exercise intervention studies in older adults examining the relationship
between cardiorespiratory fitness and brain structure and function,
typically assessed using Magnetic Resonance Imaging (MRI). Studies of
patients with Alzheimer’s disease are discussed when available. The
structural MRI studies revealed a consistent positive relationship
between cardiorespiratory fitness and brain volume in cortical regions
including anterior cingulate, lateral prefrontal, and lateral parietal
cortex. Support for a positive relationship between cardiorespiratory
fitness and medial temporal lobe volume was less consistent, although
evident when a region-of-interest approach was implemented. In fMRI
studies, cardiorespiratory fitness in older adults was associated with
activation in similar regions as those identified in the structural
studies, including anterior cingulate, lateral prefrontal, and lateral
parietal cortex, despite heterogeneity among the functional tasks
implemented. This comprehensive review highlights the overlap in brain
regions showing a positive relationship with cardiorespiratory fitness
in both structural and functional imaging modalities. The findings
suggest that aerobic exercise and cardiorespiratory fitness contribute
to healthy brain aging, although additional studies in Alzheimer’s
disease are needed.
