Are left handed people highly sensitive people? Sometimes they are.
According to the Geschwind Theory, many people who are right brained which describes highly sensitive people, are also left handed. Because right-brained children develop differently during pregnancy, some may have genetic disorders.
David Ritchey’s The H.I.S.S. of the A.S.P. Understanding the Anomalously Sensitive Person catalogued many genetic disorders that a sensitive person can have.
