Which of the following is considered a normal part of the aging process?

Strength declines is recognized as a normal part of the aging process due to physiological changes that occur as individuals grow older. As people age, there is a natural reduction in muscle mass and strength, a phenomenon commonly known as sarcopenia. This decline can affect balance and overall physical capability.

In contrast, options such as increased strength, improved memory, and heightened reflexes do not typically align with the expected changes during aging. Instead, memory may become less reliable with age, and reflexes may slow down, making the acknowledgment of strength decline as a typical component of aging particularly important for understanding the overall impact of aging on physical health.
