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.

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

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 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

lens) / focus on retina / blurred vision / blindness possible

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.
