Longevity scientist who studied hundreds of 100-year-olds shares 3 things she does to live longer 

For over two decades, Stacy Andersen, a behavioral neuroscientist at Boston University Chobanian & Avedisian School of Medicine, has delved into the lives of centenarians, seeking the elusive keys to extreme longevity. As a codirector of the New England Centenarian Study, she has traveled extensively, meeting hundreds of individuals over 100 years old to understand their secrets to extended health, Business Insider reported. While genetics plays a significant role in living to 105 and beyond, Andersen emphasises that healthy habits are paramount for reaching one's late 80s and early 90s.

Based on her extensive research, the longevity expert has integrated three key habits into her own life:

1.) Challenge yourself to learn a new skill: Andersen has taken up sailing, an activity she finds both cognitively and physically stimulating. She encouraged others to pursue new interests and said, "'Whatever you've always wanted to do that's new, go and do that!'" She noted that several centenarians she met took up painting in their later years. Engaging the brain and attention with new activities strengthens and builds neural pathways, which Andersen identifies as the number one factor for brain health.

2.) Exercise regularly: The longevity scientist makes it a point to incorporate movement into her daily routine, varying her workouts between long hikes with her dog and treadmill runs. She observes that a typical centenarian is active, with many living independently into their 90s. These individuals often drive for an average of 10 years longer and work for five years longer than their peers.
