From the late Stone Age to current times, only about 10 percent of the human population has been left-handed. Being left-handed is so uncommon that it was often viewed as a disability. Rituals, taboos, and negative connotations associated with left-handed people have been found in all languages covering the entire globe.

Wednesday on All Sides, we'll examine the impact of left-handedness on culture and human behavior.

Guests:
Kimberly Hepner, senior behavioral scientist, RAND Corporation
Howard I. Kushner, author, "On the Other Hand: Left Hand, Right Brain, Mental Disorder, and History"
Dr. Ken Beckman, Director of Corneal Surgery, Comprehensive Eyecare of Central Ohio
