Happy and Supportive Friendships

"Harvard researchers tested and retested the memories of people in their fifties and sixties over six years. Socially active people had less than half the memory loss of those who were less engaged. But quality, not quantity, of friendships matters most. If you have as many bad relationships as good ones, the stress of the bad cancels out the restorative powers of the good, suggesting your brain wants you to cull the herd to include only the happy and supportive friendships."
