Another common age-related loss is sensory deterioration, such as vision, hearing and balance. The changes often progress subtly, countered by compensatory mechanisms that offset productivity declines until the very last stages of life. A 1988 study found that bus drivers who were 60-64 years old had better safety records and fewer accidents per year than any other age group.…
In this research paper, I am going to talk about many different subtopics surrounding the human eye, such as how an eye works and some of the diseases and conditions that affect someone’s vision. I also want to find out if myopia (near-sightedness) disappears by adulthood, considering my brother has just been diagnosed with it. Plus, I am curious to see if there is some type of cure for blindness, considering how many people it must affect. First, let me explain how the human eyeball works!…

Physical changes associated with aging, beyond gray hair and wrinkles, are not always visually noticeable, are constantly changing and can affect us in many ways.…
The disengagement theory of ageing Social scientists Elaine Cumming and William Henry outlined the disengagement theory of aging in 1961. The disengagement theory discusses the processes of aging, it states that as people get into later adulthood they could experience stages of loneliness and become withdrawn from society, for example friends and family. This theory suggests that this process is a natural part of growing old. One part of the theory states that people expect or know that they are going to die one day and because people experience physical and mental decline as they approach death, it is normal to withdraw from individuals and society. The second point is that as the elderly withdraw, they receive less reinforcement to conform to social norms.…

Development though the life stages Physical effects on aging In older age (64+) many things happen on the inside and the outside the body. As you hit older age, you will start to notice that many things will happen on the outside of your body. Your hair may start to go grey or you may start to go bald. The hair goes grey because as you get older your hair loses pigment which is the colouring in your hair. Also your skin may lose elasticity; this means your skin may appear to get wrinkles. Your posture may also start to get worse in older age because your shoulders begin to drop and you may start to hunch forward. This will affect your posture.…
Mrs. L is a 64 year old female Caucasian who lives in West Texas. Her hair is naturally gray, but she dyes it, and appears thin and evenly distributed on her head. There are no signs of baldness but her hair is thinning. Tabloski (2006) states “the hair of a older person looks gray or white due to a decrease in the number of functioning melanocytes and the replacement of pigmented strands of hair with non-pigmented ones” (p. 335). Mrs. L’s skin is thin and pale in color. No other parts of her body were visible. Mrs. L is wearing trifocal glasses. She states that she started wearing them when she was 45 years old. According to Tabloski (2006), “Visual acuity tends to diminish gradually after 50 years of age and then more rapidly after the age of 70” (p. 387). She self admitted to being overweight. She appears alert, oriented, and admits that she has become more patient and tolerant. She states that she has back problems.…

P1: Explain theories of ageing M1: Compare two theories of ageing. There are many different theories explaining different aspects of aging in older adults, there are four major theories which are; psychological/social theory, stochastic theory, non-stochastic theory and biological theory. All theories have different theories included in them, I will be discussing one for each.…
The sharpness of vision gradually declines and focusing the eyes on some things close becomes difficult. Common eye disorders in the aging adult include: cataracts, glaucoma, macular degeneration, and diabetic and hypertensive retinopathy. My mother had macular degeneration and that lead to depression for my mom. She was unable to do the one thing she loved, such as reading, and without that she became depressed. She felt that with reading she could go anywhere her mind would take her and she was able to continue to learn. Not being able to read took a large portion of her life away.…

1. What are normal vision changes that occur with aging? Normal vision changes that occur with aging consist of decreased visual acuity, lessened ability to adapt to darkness and dim light, decreased accommodation to see near and far objects, loss of peripheral vision, atrophy of lacrimal glands, and difficulty discriminating similar colors. Presbyopia is the inability to focus or accommodate due to a loss of flexibility of the lens, causing decreased near vision. Cataracts are also very common in older adults; they cause the eye to have increased lens opacity in which reduces visual acuity and causes glares. Macular degeneration is the leading cause of blindness in adults over the age of 65.…
Another physical change to ageing is the wrinkling of the skin and it becomes saggy, losing firmness. This could affect an individual’s self esteem as they could have poor and negative self image. They could look at themselves in…
After years of research studying the Free Radical Theory of Aging, Harman revised this theory to incorporate the role of mitochondria in aging. This “mitochondrial theory of aging” (Lee and Wei 2012, Bereiter-Hahn 2014) encompasses the effects of cumulative oxidative damage to mitochondria induced by ROS toxicity in the organism’s lifetime. The reactive oxygen species produced from metabolic respiration are associated with detrimental effects on mitochondrial function. Mitochondrial dysfunction then leads to abnormal amounts of ROS production, which further propagates oxidative…
