Physical Change during Early Adulthood

                                         Physical Change during Early Adulthood

Physical growth is usually complete by the time people leave their teens; but for some parts of the body, the process of aging actually begins long before this time. For example, the lenses in our eyes begin to lose flexibility by the time we are only twelve or thirteen years old. For some people, the tissues supporting their teeth have already begun to recede and weaken even before they have attained full physical maturity. So, aging, like growth, is a continuous process that starts very early in life.

Such change occurs quite slowly at first, but then proceeds more rapidly in later decades. Muscular strengths, reaction time, sensory acuity, and heart actions and output are all at or near their peaks through the mid-twenties and then decline- slowly – through the mid – thirties. Many members of both genders do experience considerable weight gain during early adulthood, and some men undergo significant hair loss. By and large, however, physical change is relatively slow during this stage of life.
