I believe that intelligence and creativity, inventivity (?) does not depend
on the SIZE but the FUNCTION of the brain....
And on how you maintain the "hardware" (brain) biochemically, and how you
use the "software" (intellectual knowledge) in a kognitive way. Includes
being broadminded and open to new ideas and new paths.
Einstein was a creative genius, but he had a little brain when compared to
many rather average individuals that lived at the same time.
