This book aims to develop a critical and caring look at the elderly, a social character of great importance because it is the reflection of the complete human development, which has different physiology, cognition and behavior because the body changes over time and we must understand these changes to better adapt, always seeking the physical and psychological well-being. I hope to develop in the reader knowledge that can help in the dynamics of caring for the elderly, the understanding of their limitations and the perspective that old age is a natural process of the human body.
