Here’s another reason to call your buddies up for coffee.

Researchers from the United States have found that social ties, along with exercise, preserves memory in the hippocampus. The hippocampus is a region in the brain that is associated with memory, emotions and motivation and which declines with age even in the absence of illness.

Lead researcher Elizabeth Kirby from the Neurological Institute at Ohio State University-Columbus said their studies on mice found that those which lived in groups of six had healthier brains and better memory.

Similarly, Singapore researchers found in a study of 46 seniors that social isolation puts them at risk of developing depression, and could affect their cognition level, quality of sleep and ability to perform their daily activities.
