Old People Should RetireRetire So That YoungerYounger People Can
Work?
Why study the effects of aging? (5 reasons):
• biology of aging (genetic and environmental factors associated with aging)
• shift in survival and life expectancy has itself driven the inquiry about the social implications
• medical science documents the diseases of old age and attempts to moderate their effects
Aging
• health care costs of an older society
• psychologists attempting to understand the negative attitudes toward the elderly
Old People Are SlowSlow And Get In My Way!
Old People Aren’t BeautifulBeautiful!
The Changing Face of the Nation
• Baby Boomers approaching retirement.
• Elderly are living longer - combination of modern medicine and lifestyle related factors = age 115 years
Changing Face of the Nation
• higher quality of life - therefore older people are a major social, political and economic factor in society.
• Changing demographics also reflected in fact that not as many children are being born in first world countries.
I Will NeverNever Get That Old!

THEORIES ON AGING
Biological:
• the wear and tear theory – “ It’s Not the Years.., – “ It’s Not the Years.., It’s the Mileage”It’s the Mileage”
• the human body simply the human body simply wears outwears out
• some activities may some activities may predispose this condition predispose this condition (running)(running)
THEORIES ON AGING
• the cellular theory – limited number of cells / capacity to reproduce / once exhausted body begins to deteriorate / varies from individual to individual
• the autoimmune theory – declining immune system / loses control attacking body
THEORIES ON AGING
• the genetic mutation theory – the older you are the more mutant cells develop/ function differently than intended / dysfunction of body organs + systems
Physical Changes
The Skin:The Skin: • (30’s)thinner + loses elasticity
/(40’s) lines on the face /• (50’s) crow’s feet /(60’s) loses
colour + sags / (70’s) age spots etc.
Bones and Joints:• constantly changing constantly changing
accumulating and losing minerals accumulating and losing minerals (modeling)(modeling)
• 30’ and 40’s – net loss of minerals 30’ and 40’s – net loss of minerals – could lead to osteoporosis– could lead to osteoporosis
Physical Changes
OSTEOPOROSIS:• loss of bone material /
bone mass• post-menopausal women• fractures common• very debilitating• risk factors: calcium, lack
of exercise, lack of estrogen therapy post-menopause
Physical Changes
The Head:The Head: • features of the head
enlarge ( nose, ears, head - skull thickens)
Brain shrinksBrain shrinks
The Urinary Tract:The Urinary Tract:• urinary incontinence • individual • treatable - drug therapy
Physical Changes
Heart and Lungs:• Resting Heart Rate stays about
the same throughout life• stroke volume decreases • heart muscle deterioration• Vital Capacity decreases
(max. inhalation + exhalation)• exercise slows these changes
Eyesight:Eyesight:• 30 years of age – lens harden • 40 years of age – lens: yellow
and looses transparency• Cataracts – (clouding of the
lens) / focus on retina / blurred vision / blindness possible
• glaucoma – ( increased pressure within the eyeball)
• hardening of the eyeball , impaired vision, eventual blindness

individual, characterized by group of symptoms :individual, characterized by group of symptoms :
• memory loss
• loss of language functions
• inability to think abstractly
• inability to care for oneself
• personality change
• emotional instability
• loss of sense of time
ALZHEIMER'S DISEASE
• three quarters (75%) dementia’s caused by Alzheimer's disease - chronic, degenerative dementing illness / cause unknown
• no known cure to stop the progression
• 6% of people over 65 years have Alzheimer's disease
• Alzheimer's disease 4th leading cause of death - older adults
• < seventy conditions can cause dementia
Types of Dementia:
• Degenerative = Alzheimer's, Parkinson's, Huntington's.
• Vascular dementia: cerebral embolisms, blood clots, and infarctions.
• Traumatic dementia: head injuries.
• Lesions: tumors, hematomas, and cancers.
• Toxic dementia: alcohol, poisons.
• Others: epilepsy, post-traumatic stress disorders, and heat stroke.
THEORIES OF AGING:
• Brain size & longevity
• Biological clock determines how long we live.
• Disposable soma: Allocation of resources - optimal is as little as possible to body repair, and more to other functions.
• Wear and tear: Accumulated damage leads to breakdown - like a machine!
Genes and AgingGenes and Aging
• Genetic theories: Loss of genetic info. over time = loss of protein to rebuild.
• Immunological: Breakdown of immune system.
• Others: Error accumulation, cell loss, nutritive, environment, and brain chemistry.
