What could be an example of the result of Senescence?

Senescence refers to the process of aging and the gradual decline in physiological functions and biological activity. It is characterized by various physical changes in the body, one of which is joint stiffness. As individuals age, joint stiffness can occur due to the wear and tear of cartilage in the joints, loss of synovial fluid, or the development of conditions such as osteoarthritis. This results in reduced flexibility and mobility, which can significantly affect the quality of life.

In contrast, increased energy levels, increased metabolism, and rapid growth are generally associated with youth or healthier physiological states, rather than the aging process. These conditions would not typically be expected outcomes of senescence, thus reinforcing why joint stiffness is a direct and relevant example of the consequences of the aging process.
