The more we exercise the brain the more it grows. Physically. Throw new stuff in and the dendrites make more connections. So interacting socially morphs the brain. New thinking means new brain cells means new pathways. Four in an hour is said to make the pathways permanent. Go meet people. Exchange. Grow young and old simultaneously. Young for new stuff, old for perspective. Biologically in its brain cells, encompassing of previously unanticipated worlds, a complex society is growing.
