P1: Make clear theories of ageing M1: Compare two theories of ageing.
There are many different hypotheses explaining different factors of aging in elderly adults, you will find four major theories which are; psychological/social theory, stochastic theory, non-stochastic theory and neurological theory. Every theories will vary theories contained in them, I will be discussing one for each and every.
Disengagement theory (Psychological theory) is mostly based upon a gradual disengagement of the individual from your society. Disengagement theory states that individuals under your own accord withdrawal from society, in fact it is expected that they can withdrawal simply by society if they slow down simply by retiring. This theory promises that aged individuals systematically disengage off their previous cultural roles because they realise that death with the near future. The theory further shows that society responds to this mutually as of recognition that the specific will soon pass and the young generation has to come take control, so they can function in their absence. Disengagement theory has seven postulates to clarify why it truly is rational for individuals to little by little as their age group passes to begin anticipating their particular deaths and start to disengage, so the new generation usually takes over and replace their job roles. Another theory can be wear and tear which can be the stochastic theory, this theory even comes close the human body to a machine and argues that it simply wears out because of constant work with. This theory claims that aging can be caused by progressive accumulation of injury by different factors, just like mechanical damage. Dr Aug Weismann initial introduced this theory in the year of 1882, his theory was that your body and its cellular material were ruined over time by overuse and abuse. He also said that it was not just the constant use which usually damaged the entire body, it was toxins in our diet and in the environment. For example the increased consumption of fat, sweets, caffeine, alcoholic beverages and pure nicotine, by the ultra-violet rays of the sun...
