Aging - Essay Example The questions have been in the mind of people for a century. However, despite the studies in the genetics and molecular biology, the mystery of controlling the lifespan of human is yet to be found (Nouwen & Gaffney, 2004). Many literatures have been put forward to explain the aging process, but none of them has been a success. The conventional aging literature believes that aging in not a genetically programmed. Modern theories in biological aging in humans can either be an error theory or a programmed theory. The programmed literatures believe that aging comes with a biological timetable, perhaps the continuous one in regulating the childhood development and growth. The regulation will depend on the expression of genes affecting systems that are responsible for defense response, maintenance, and repair. The damage theory emphasizes the assault of environment to the living organisms inducing the cumulative damage at different stages as the reason for aging (Cox, 2005). The programmed literature has three different categories; programmed longevity, endocrine theory, and immunology theory. According to programmed longevity, aging arises from sequential putting on and off for some of the genes. According to endocrine theory, the immune system can be programmed to decline with time, which arises to a rising vulnerability to diseases that are infectious and therefore aging and later death. It is researched that the immune system effectiveness peaks during puberty and slowly declines with the age advance. For instance, when a person grows older, the antibodies will lose effectiveness, and very few diseases will be combated by the body effectively, which leads to eventual death and cellular stress. The deregulated response of the immune has been connected to inflammation, cardiovascular disease, cancer, and Alzheimer’s disease. Although direct relationship is yet to

Therefore, the need for mental health improvement on the general population is important; as its related challenges need to be addressed; for instance, stigma and human rights. Studies on the psychiatric population have been conducted over the past years, including the causes, symptoms, and treatment. According to Stewart, et al (2009 p749), manual restraining was commonly used in Psychiatric hospitals as a way of managing violent behaviors of the patients. Violent behaviors among the psychiatric patients are usually high; therefore, manual restraint is commonly used to calm the patient down. This method involves restraining the patient on the floor in a prone position to restrict any movement; however, such reaction lasts for about ten minutes. Stewart et al (2009) further insist that manual restraint involves the risk of injury to the involved parties, but are common in staff members. According to a survey conducted on 269 nurses in the psychiatric care units, they agreed to the fact the manual restraint had positive outcomes, although it was stressful (Stewart, et al, 2009, p.753). Mental disorders are not only evident in adults, but also among
