Why Are You Left-Handed or Right-Handed? is presented by Osher Lifelong Learning Institute (OLLI) 

$15 (plus $25 OLLI membership required)

Most people — 85% to 90% — are right-handed and have been since the Stone Age. This session will focus on the genetic, neurological, and cultural factors that influence our preference for using one hand over the other, and what can be inferred from that preference. We will examine when handedness emerges in children and age-related changes in hand dominance.
