Preparing for Aging, Death, and Dying

• Aging refers to the patterns of life changes that occur in members of all species as they grow older.

• Some believe aging begins at the moment of conception, others believe that it does not begin until we reach our forties.

• The study of individual and collective aging processes is called gerontology.– Explores the reasons for aging and the ways

in which people cope with to the process.


Characteristics of People Who Age Successfully

• They stay active, through leisure activities and regular exercise.

• They maintain a normal weight range.• They eat a healthy diet containing low

levels of saturated fats, with plenty of fruits, vegetables, and whole grains.

• They participate in meaningful activities, like volunteering and other social activities.

• They don't smoke, and consume alcohol only in moderation.


Older Adults: A Growing Population

• Its not how many years someone has lived, but how much life the person has packed into those years.

• Life expectancy for a child born in 2011 is 78.4 years, over 30 years longer than for a child born in 1900.

• Today, there are 39.6 million people aged 65 or older, making up 12% of the population.

• By 2030,the older population is expected to be twice as large as in 2008, growing to 72.1 million and representing 19.3% of the population.


Theories of Aging

• Wear-and-tear theory– Like everything else in the world, the human body wears out.

• Cellular theory– At birth we only have a certain number of usable cells,

programmed to reproduce a limited number of times.

• Genetic mutation theory– The number of body cells exhibiting unusual or different

characteristics increases with age.

• Autoimmune theory– Attributes aging to the decline of the body's immunological

system.


Physical and Mental Changes of Aging

• Typical physical changes– Skin– Bones and joints– Head and face– Urinary tract– Heart and lungs– Senses– Sexual function (men and women)


Mental Function and Memory

• Dementias and Alzheimer's Disease– Dementias are progressive impairments that interfere

with memory and normal intellectual functioning.– Alzheimer's disease is a chronic condition involving

changes in nerve fibers of the brain that results in mental deterioration.

• The key to maintaining memory is keeping your mind active. – People who engage in reading, solving mental

puzzles, and learning to play musical instruments have a better chance of keeping their memory sharp.


Alcohol and Drug Use and Abuse

• A person who is prone to alcoholism during his or her younger years is more likely to continue that pattern during later years.– Alcohol abuse is five times more common among

older men than among older women.

• Older people rarely use illicit drugs, but some mistakenly overuse or misuse prescriptions. – Polypharmacy—use of multiple medications


Strategies for Healthy Aging

• Develop and Maintain Healthy Relationships– Social bonds and support lend vigor and

energy to life.

• Enrich the Spiritual Side of Life– Developing bonds with nature, the

environment, a higher being, and yourself is important.

• Improve Fitness– the less muscle you have, the less energy you

will burn even while resting.


Strategies for Healthy Aging, (cont.)

• Eat for Health

• Certain nutrients are essential to healthy aging.– Calcium – to prevent bone loss– Vitamin D – for calcium absorption– Protein – for muscle mass– Healthy diet should help meet all other

nutrient needs.


Dying and Death

• Death is the final cessation of vital functions.• The Process of Dying

– The process of the decline in body functions that results in the death of an organism

– It is complex and includes physical, intellectual, social, spiritual, and emotional dimensions.

• Coping Emotionally with Death– Stages of dying

• Denial- “Not me, there must be a mistake”• Anger- “why me?”• Bargaining- “If I’m allowed to live, I promise….”• Depression- “It’s really going to happen to me, and I cant do

anything about it”• Acceptance- “I’m ready”


Social Death

• Social death can occur when a person is not treated as an active member of society.– People who are treated differently when they

are dying, leading them to feel more isolated and unable to talk about their feelings:

• As if he or she were already dead.

– Loss of being valued or appreciated by others– Denying a person normal social interaction


Coping with Loss

• Coping with the loss of a loved one is extremely difficult, for the dying person, as well as close family and friends, frequently suffers emotionally and physically from the loss of critical relationships and roles.

• Bereavement: the loss or deprivation experienced by a survivor when a loved one dies

• Grief: an individual's reaction to significant loss, including one's own impending death, the death of a loved one,

• Mourning: the culturally prescribed behavior patterns for the expression of grief


Worden's Model of Grieving Tasks

• Accept the reality of the loss.

• Work through the pain of grief.

• Adjust to an environment in which the deceased is missing.

• Emotionally relocate the deceased and move on with life.


The Right to Die

• Advance directives are documents that stipulate an individual's wishes about medical care; used to make treatment decisions when and if the individual becomes unable to voice his or her preferences.

• Living wills are a type of advance directive.• A living will includes specific wishes about dying.

– Be specific.– Get an agent.– Discuss your wishes.– Deliver the directive.
