• Sarcopenia is an age-related gradual loss of muscle mass and strength, a type of muscle atrophy primarily caused by the natural aging process. It is one of the most important causes of functional decline and loss of independence in older adults. Being physically inactive and eating an unhealthy diet can contribute to the disease. • Chronic Obstructive Pulmonary Disease (COPD) is a common age-related disease. It is typified by a reduction of airflow into the lungs due to the inflammation of airways, thickening of the lungs lining, and an over-production of mucus in the air tubes. • Cognitive decline producing mild short-term memory loss, difficulty finding words, and slower processing are all normal features of aging. Deviations from normal brain aging may lead to dementia, manifesting as memory loss, mood changes, confusion, communication difficulties, or deprived judgment. Rates of dementia rise with age. Alzheimer's disease is the most common cause of dementia 307 , but a number of other disorders such as vascular dementia, Lewy body dementia, frontotemporal disorders, Huntington's disease, and Parkinson's disease can trigger it as well.
