What The World’s Longest Running Personality Study Reveals About Our Lives

“Over the course of a lifetime, just as your physical appearance changes and your cells are constantly replaced, your personality is also transformed beyond recognition.”

Quartz details the findings of the world’s longest running personality study and reveals that we become completely different people when we age, calling into question ideas of the “self” and pointing out our own younger self will likely be unrecognizable to our older self.
