What are some examples of the physical and cognitive changes people go through when they enter late adulthood? To avoid any confusion and to more clearly represent my personal opinions, perspectives and points of view, I think it necessary to divulge my age. I turned 55 on December 25, 2012. I must say that hitting 55 was a mental challenge for me. AARP considers the age of 55 to be Senior Citizen Status. May restaurants give discounts to their patrons who are 55 years of age or older. Our text sites many theories on aging and I have read them all. Since no one knows exactly why we age and die, there is no correct answer to the aging theory. I subscribe to the Damage Theories and specifically the Wear-and-Tear Theory. In quoting our text it suggests that Damage Theories relate to internal, microscopic damage to the organism and is responsible for death. We know that with use, machinery like cars and dishwashers break down. There is no definitive research linking death to wearing out, but it is one of the most common explanations people have about death. This view is called the wear‐and‐tear theory. Of course, the body is not a machine. Although the human body is constantly creating new cells and getting rid of old ones, this theory suggests that some vital parts do wear out.” Physical & Cognitive changes of aging
• Major age related changes occur in nearly every major system of our bodies. – external (or observable)
– internal (those that are not directly observable).
• do not necessarily happen independent of each other.
– we do not begin to notice the decline in the systems until our 30s or 40s. – Injuries take longer to heal, we are sorer after strenuous exercise, we tier faster, may not be as strong or fast and may need more time to “cool down” after exercise. – compensated for with knowledge and skill
• Changes in our physical systems are gradual – taking time to happen • Two Basic Principles of normal aging
– The rates at which we all age vary dramatically.
– Second there is great variability of aging patterns.
• There are many possible paths to aging
• We must not always think of physical aging in terms of losses – – there are systems that may remain stable throughout later life. • the dominant theme of physical aging is that of decline. Skin
– One of the most obvious signs of aging are changes in the skin – blemishes (age spots), wrinkles, and sagging.
• “crows feet”
– the sun and exposure to ultraviolet rays – photoaging – skin tends to bruise easier and the bruises may take longer to go away. – The skin is rougher, dryer, and losses it’s uniform color. Hair
• Over the course of time many people’s hair will begin to gray and thin. – Graying –
• hair on the entire body can go gray.
• decreased melanin production in the hair follicles
Gender differences in Graying
• Graying for male is often seen as a sign on wisdom and prestigious. … • Psychological impact
• seen an just another sign of aging, the loss of youthfulness etc.. • Psychological impact
Hair loss or thinning
• Males – Male pattern baldness
• (beginning at the temples then moving to the back of the head) – hair on the rest of the body may become thicker
– psychological impact of hair loss
– some loss of hair on their head or thinning.
– There is also increased hair growth on the chin and upper lip in many women Height
• Standing height is reduce –
– most dramatically following after the 50s-
• Males will loss about ½ inch between 30 and 50 and then another ¾ inch between 50 and 70 • Women may loss as much as 2 inches between 25 and 75
– The psychological aspects.
• Total body weight increase until the mid-50s then begins to decline. – Weight loss in later years is not due to a sliming of the torso but a loss of muscle mass and bone.
• Due to changes in the larynx, respiratory system and muscle...
