Researchers are more optimistic than ever about the potential of the aging brain. For example, the brain can grow new nerve cells—neurogenesis. Studies of older people who have maintained mental acuity revealed common characteristics. They tended to be:
- Socially connected, with strong ties to relatives, friends and community
- Both physically healthy and physically active
- Engaged in stimulating or intellectually challenging activities.
