Ellen Jane Langer: Our limits
It is not primarily our physical selves that limit us but rather our mindset about our physical limits.
Ellen Jane Langer (born March 25, 1947) is a professor of psychology at Harvard University; in 1981, she became the first woman ever to be tenured in psychology at Harvard. Langer studies the illusion of control, decision-making, aging, and mindfulness theory. Her most influential work is Counterclockwise, published in 2009, which answers the questions of aging from her extensive research, and increased interest in the particulars of aging across the nation.
