Scientists can now credibly say that the early childhood years – from birth to age 5 – lay the foundation for later economic productivity, responsible citizenship, and a lifetime of sound physical and mental health. Conversely, deep poverty, abuse, neglect, and exposure to violence in early childhood can all lead to toxic stress.
经过多年的研究，科学家发现，人类在0到5岁期间的早期教育对日后谋生能力，社会责任感和心理生理的健康起着十分重要的作用。反之，如果在儿童时期，孩子遭受过分的贫穷，虐待和漠视以及暴力等，将会给他的一生都会有负面的压力。
