Unavoidable Changes In Middle Adulthood

A lot of changes occur in middle adulthood, which spans the ages of 40 to 65 (Rathus, 2016). People do not age at the same rate or in the same way, and this is known as interindividual variability. Unavoidable physiological aging is characterized by changes in hair, skin, and nails, senses, reaction time and lung capacity (Rathus, 2016). Other changes can be moderated and even reversed through diet and exercise, including metabolism, muscle mass, strength, bone density, and aerobic capacity. Diet and exercise are crucial in maintaining good health throughout life, but especially during middle adulthood. Regular exercise can expand breathing capacity, compensate by increasing the size of remaining muscle cells, and expands aerobic capacity (Rathus,
