Constance is 75 years old and still very active. She gardens, hikes, plays chess, and is learning to play the piano. She exercises daily to stay fit. She loves reading, listening to music, and playing with her grandchildren. Her hearing and eyesight are not what they used to be, and she is not as steady on her feet as when she was younger. She wears a hearing aid, eyeglasses, and sensible shoes to minimize these losses. Researchers would say that Constance is a good example of how development includes:
growth, maintenance, and regulation of loss.
