Maintaining social connections is crucial for a long and healthy life, potentially adding two extra healthy years for social 80-year-olds compared to their less social peers. According to Vilhelm Bohr, a 74-year-old doctor and adjunct professor at the University of Copenhagen with over 35 years of experience in aging research, social interaction is a key factor in longevity, even more so than diet or exercise.

Research from Japan, a country with one of the highest life expectancies in the world (over 84.7 years), supports this claim. While previous theories focused on high fish or fruit consumption, current understanding emphasizes the importance of social interaction among older Japanese people.

Bohr highlights the ongoing advancements in aging research. He and his colleagues recently published a study on Werner’s syndrome, a rare disease causing accelerated aging, and found that NAD supplementation, a dietary supplement supporting DNA repair, could potentially help patients. Studying patients with Werner’s syndrome has allowed researchers to identify specific proteins and functions that malfunction during aging, providing insights into normal aging processes.

While the exact mechanisms by which social activity prolongs life remain unclear, research suggests it involves connections between nerve cells and brain stimulation. Bohr also points to the importance of stimulating the brain to preserve it, referencing an Alzheimer’s study. He suggests that the role of the senses, particularly the sense of smell, may be an overlooked factor in aging.

Bohr stresses the value of engaging in physical activities with others, citing examples like Japanese walking and Mahjong, which are popular among older Japanese individuals. He also expresses skepticism about fasting trends due to the risk of missing out on important social interactions during meals.
