According to the programmed theory, aging depends on one’s biological clock (Jin, 2010). As a sub-category of the programmed theory, the immunological theory is one that can be applied to both Mr. S and Mrs. M. This theory notes a decline in the immune system overtime, which leads to increased vulnerabilities to infections, decreased counteraction against diseases, …show more content…
For both Mr. S and Mrs. M, the sub-category of the damage and error theories known as wear and tear theory can be applied because their bodies have gone through repeated use (Jin, 2010), which can be due to working conditions, stress, physical activity level, possible injuries, and medical conditions, such as increased workload of the heart for Mr. S who has fluid retention or joint pains that Mrs. M feels because of her RA. Another sub-category of damage and error theory that can be applied to both Mr. S and Mrs. M is the rate of living theory, which notes a shorter lifespan with greater rate of oxygen basal metabolism. Since Mr. S suffers from fluid retention and has heart disease this leads me to believe that he is not managing his medications properly and is slowly headed towards right- sided heart failure, which could also be due to left sided heart failure. This means that Mr. S is prone to having dyspnea, poor oxygenation, increased respiratory rate and therefore increase consumption of oxygen. As for Mrs. M, she suffers from RA, which can be painful. Pain can lead to increase respiratory rate, increase need for oxygen, and increase consumption of oxygen. Lastly, both Mrs. M and Mr. S suffer from some form of stress (physical or emotional) and this stress can lead to free radicals; therefore, the free radical theory can also apply to both as causes of
