Gradually, the muscles become smaller, drier, and capable of less forceful contraction. By age eighty, nearly half the muscle mass has atrophied, due to a decline in motor neuron activity. Diminishing muscular strength slows reflexes.

A gerontologist studies the aging process and the challenges and changes associated with aging, including physical, mental, and emotional aspects. They may focus on improving quality of life for older adults and developing strategies for successful aging.
Aging typically leads to a gradual decline in glomerular filtration rate (GFR) due to changes in kidney structure and function. This decline is a normal part of aging and is often associated with a decrease in the number of functioning nephrons and reduced renal blood flow. This reduction in GFR can contribute to age-related kidney diseases and changes in medication dosages in older adults.
Physical changes associated with aging can sometimes lead to a decline in self-esteem and self-confidence, as individuals may struggle with accepting changes in their appearance or abilities. However, self-esteem and self-confidence can also improve as people develop wisdom, resilience, and acceptance of themselves over time. It depends on the individual's mindset, support system, and ability to adapt to these changes.
