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.
Disengagement theory (Psychological theory) is mostly based upon a gradual disengagement of the individual from the society. Disengagement theory argues that individuals voluntarily withdrawal from society, and it is expected that they will withdrawal by society when they slow down by retiring. This theory claims that elderly individuals systematically disengage from their previous social roles as they realise that death is in the near future. The theory further suggests that society responds to this mutually as of recognition that the individual will soon pass and the younger generation needs to come take over, so they can function in their absence. Disengagement theory has nine postulates to explain why it is rational for individuals to slowly as their age passes to begin anticipating their own deaths and start to disengage, so the new generation can take over and replace their job roles. Another theory is wear and tear which is the stochastic theory, this theory compares the human body to a machine and argues that it simply wears out because of constant use. This theory claims that aging is caused by progressive accumulation of damage by various factors, such as mechanical wear and tear. Dr August Weismann first introduced this theory in 1882, his theory was that the body and its cells were damaged over time by the overuse and abuse. He also claimed that it wasn’t just the constant use which damaged the body, it was toxins in our diet and in the environment. For example the excessive consumption of fat, sugar, caffeine, alcohol and nicotine, by the ultra-violet rays of the sun...
