As people age, it is common for them to experience certain physical changes. Gray hair is a natural sign of aging as the pigment cells in the hair follicles gradually die. Bladder leaks, also known as urinary incontinence, can occur due to weakened pelvic floor muscles and decreased bladder control. Decreased muscle tone is a result of age-related muscle loss, known as sarcopenia. This can lead to a decrease in strength and overall muscle function. A slower gait, or walking speed, is often seen in older adults due to changes in muscle strength, balance, and coordination. These signs collectively indicate the normal aging process.
