HOW TO MANAGE EFFECT OF AGEING
Ageing: This is the process of becoming older. The term refers especially to human beings, many animals and fungi, whereas for example bacteria, perennial plants and some animals are potentially immortal. In the broader sense, ageing can refer to single cells within an organism which have ceased dividing or to population of a species.
In humans, ageing represent the accumulation of changes in a human being over time, compassing physical, psychological, and social changes.
The causes of ageing are uncertain; current theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes (such as DNA methylation) may cause ageing. Programmed ageing shouldn’t be confused with programmed cell death.
EFFECTS OF AGEING
*Enlarged ears are noses of old humans are sometimes blamed on continual cartilage growth, but the cause is more probably gravity.
* Teenager lose the young child’s ability to hear high frequency sounds above 20 kHz.
* Cognitive decline begins in the mid-20s.
*Wrinkles develop mainly due to photo aging, partially affecting sun exposed areas (face).
N/B: photo aging/ photo ageing is the characteristic changes to skin included by chronic UVB exposure.
*After peaking in the mid-20s, female fertility declines.
*people over 35 years of age are at risk of developing presbyopia and most people benefit from reading glasses by age 45-50. The cause is lens hardening by decreasing level of a-crystalline, a process which may be sped up by higher temperatures.
*Atherosclerosis: this is classified as an ageing disease. It leads to cardiovascular disease (for example stroke and heart attack) which globally is the most common cause of death.
*The maximum human life span is suggested to be 115 years for the fore seeable future. The oldest reliably recorded human was JEANNE CALMENT who attained 112 years and died on 1997.
Dementia becomes more common with age. About 3% of people between the ages of 65 and 74, 19% between 75 and 84 and nearly half of those over 85 years of age have dementia.
*Age can result in visual impairment; whereby non-verbal communication is reduced. Which can lead to isolation and possible depression. Vision loss increases with age and affects nearly 12% of those above the age of 86.
N/B: A distinction can be made between “proximal ageing” (age-based effect that come about because of factors in the recent past) and distal ageing (age based differences that can be traced to a cause in person’s early life, such as childhood.
Ageing is among the greatest known risk factors for most human diseases of the roughly 150,000 people who die each day across the globe, about 2/3rd -100,000 per day die from age related causes. In industrial nations, the population is higher, reaching 90%.
DEALING EFFECTIVELY WITH AGE.
Ageing is not a disease; it is a biological processes of change that starts at birth. The ageing process means that people may not have the same strength or physical abilities at 50 or 60 that they had at 25 or 30. But in the case of most jobs, with minor adaptations or adjustments, workers can perform the very well into their 70s and sometimes beyond.
Age doesn’t determine fitness with regular physical exercise, physical capacity can remove relatively unchanged between ages 45 to 65. It also means that 45 years old workers who don’t exercise can be less fit than co-worker aged 65 or older who do look after their health.
Workers of any age can experience emotional or psychological stress in the work place. While there are many potential sources of workplace stress, some causes of stress might be more specific to older workers example;
*feeling threatened by younger workers or supervisors.
*Coping with negative attitudes about ageing.
*Being concerned with retirement plans.
