A study found that more intelligent individuals had brain networks with more stability, as shown by less fluctuations on fMRI scans. Increased stability of networks may indicate a protective mechanism of the brain.

Autophagy is a process that eliminates cell waste to prevent toxic build-up. It has been shown to be closely related to many of the hallmarks of aging, while maintaining immune function and controlling inflammation.

Older adults with hypertension on a more aggressive treatment regimen saw a reduction in accumulation of brain white matter and cardiovascular events by lowering systolic blood pressure to 130 mmHg.

Adults who walk more slowly have markers of accelerated aging, including looking older. Increased aging of the lungs, teeth, immune system, and cognitive function were correlated with slower walking speed.
