What is it, precisely, that makes you unique? TIME probes the science
of human development in search of answers and identifies the major
factors that shape your personality and thought patterns. Learn why some
people are introverts and others extroverts and why some people lack
confidence while others have it in abundance. Discover how genetics,
physicality, brain function, family, cultural and social
influences-including surprising factors such your dreams and what you
consume-define the science of YOU.
