Staying intellectually curious is key to maintaining a sharp mind as you age. This means continuing to learn and explore new things, whether it's through reading, taking classes, or engaging in new hobbies. Staying socially connected is also important, as research has shown that social isolation can contribute to cognitive decline. Make an effort to stay connected with family, friends, and loved ones, and seek out new social connections through volunteering, joining a club or group, or participating in other community activities.
