Understand the typical physical changes that occur during middle adulthood, which generally ranges from about 40 to 65 years of age.
Recognize that peak muscle strength and flexibility usually occur earlier in adulthood, often in the 20s or 30s, so this is not a sign of aging in middle adulthood.
Recall that puberty is a developmental stage that happens during adolescence, not middle adulthood, so onset of puberty is not relevant here.
Consider common sensory changes in middle adulthood, such as a gradual decline in visual acuity, especially difficulty seeing objects up close, which is known as presbyopia.
Note that rapid increase in height is characteristic of childhood and adolescence, not middle adulthood, so it is not a sign of aging in this stage.
