Why does time go by so fast when you get older?



Chapter 1

Major Issues

• demographic shifts in balance of young vs. old

- not limited to US (generation X/ baby boomers exceed millennials) • implications for our culture

- interpersonally/psychosocially: perceptions of majority/minority group -politically/economically: social security, medicare

• microaggression: demeaning; not paying attention to someone or failing to treat  them like a human being  

• normal/primary: successful aging(biology)

• secondary/pathological: lifestyle, able to control it


Is stimulation important for brain development?



- distinctions between the two above are difficult to make

• tertiary aging: distance from death rather than distance from birth - rectangular aging curve

*co-morbidity: multiple problems (heart disease, diabetes)

Aging Scale

optimal(good)—> normal/primary(average)—>secondary/pathilogical(bad)

• rectangular aging curve: this says that someone ages perfectly and dies only when  their biological clock runs out; it is a continuous line for healthy aging(no decline) and  then a straight drop off for death; this type of aging is highly unlikely


What is the importance of empathy and perspectives of others?



- usually, the line looks more like stairs because people age slowly and quickly at  certain points in their lives because of different experiences

• normal aging

- inter individual differences: fan effect; differences between people - intra individual differences: differences in one person overtime If you want to learn more check out How william butler yeats irish identity shaped his poetry?

- fan effect

• generational stereotypes

- stereotypes: generalizations, can be positive or negative

- most ageism is linked to greater involvement in risky behavior among younger  adults

- nobody is immune to stereotyping  

- generational differences emphasized over similarities  

empathy vs. perception of separateness: being aware of other peoples  value systems

2We also discuss several other topics like What is american culture?

• Person-Environment Context (P-E-Fit): allows us to understand aging in context - people who are skilled are not stimulated enough in a bad environment - people who are not skilled can get too overwhelmed in a bad environment  - you have to find the environment that fits with that person We also discuss several other topics like What is an expansion upon freezing?

Fat Cells  

• Fat Chance by Robert Lustig

- MD (medical doctor)

*DO: doctors who use more alternative methods

- pediatric endocrinologist (hormones and glands)

• doctors are under the control of:

- pharmaceutical companies

- insurance companies

- government

• adipose tissue: fat tissue

• adipocytes: fat cells

fat cells stage 1: cells are depending on one artery for blood supply  

- contains M2 macrophages; not activated because there is no debris to  pick up/eat

fat cells stage 2: hypertrophy: fat cells get bigger, increase in macrophages - contains M2 macrophages and M1 macrophages: pick up/eat debris

fat cells stage 3: apoptosis: programmed cell death (if cell gets too stressed out) to  protect healthy cells; sends out warning signals, MCF-1 attracts macrophages  If you want to learn more check out What is the puritan community?

- contains M1 macrophages to clean up dead or dying cells

Sugar Metabolism  

• fructose  

- comes from nature

- cheap to make  

• HFCS: sugar from corn

• excess sugar:

- liver handles it (largest organ in visceral cavity)

- handles glucose metabolism

- sends sugar into bloodstream for energy ATP

- mitochondria makes ATP; packages glucose molecules as glycogen  (100g) We also discuss several other topics like What are the major parts of the digestive system?

- stored in skeletal muscles (600g) lasting approximately 1.5 days

- carbs (glucose) become fat in the liver; plastic fat: saturated fat (fatty acids)  - triglyceride: backbone with 3 fatty acids attached to it  If you want to learn more check out What is the meaning of hydrolysis in biology?

- packed in VLDL(very low density) molecule—>turns into LDL after it  dumps its load into the cell

- has to be taken apart to go into a fat cell

- starts secreting pro-inflammatory cytokines(go everywhere)  

- this can cause heart disease

Peristalsis: muscular movement of food  

ex: sugar

oral cavity(sugar starts being digested by amylase)—> esophagus(smooth muscle) (longitudinal and circular muscles)—> sphincter(prevents stomach contents from  coming up out of stomach)—> stomach—> sphincter—> small intestine (sugar is  now glucose)(glucose goes through intestinal wall into blood stream)—>  pancreas( secretes digestive juices in stomach, secretes insulin-beta cells)

Diabetes  

• Type l: inheritable, can’t make insulin

• Type ll: insulin resistant; insulin doesn’t work well, cells become resistant to insulin  (primarily due to lifestyle)

• Type lll: brain cells become resistant to insulin (leads to dementia); cells that control  cognition have been starved of glucose  

*diabetes is usually not diagnosed until approximately 28 years of age 3
