brain ageing slowed due to increased social interactions
Slower brain ageing and memory preservation linked to higher social ties - short science articles

Researchers have found that mice that are grouped together have better memories and healthier brains compared to mice which live in pairs. Grouped mice performed better on experiments that tested identification of objects moved to a new place and also developed better escape strategies in maze based memory tasks. Further pair housed mice had higher signs of inflammation in the brain tissue as compared to group-housed mice indicating that the later had better cognitive health. This research supports the notion that social connections indeed help in preserving the brain health.
