Scientists have long thought that the number of brain cells was fixed from childhood, but have now discovered that new brain cells can indeed appear even in adults.
So on this day, a new brain cell is born in a man’s skull, and it finds itself in a gigantic dark and empty cave.
“_ Is there anybody?”
“_…body…body” answers the echo.
“_Am I all alone?”
“..lone …lone” answers the echo.
Completely desperate, he sits on the cave’s floor and starts weeping.
But suddenly, he hears quick footsteps and a panting brain cell arrives and asks:
“What are you doing here? We’re all downstairs!”
