Document Summary
Last chapter 18 -adulthood & later years -aging. Introduction: in 1921, ~1/20 people were 65+, now 1/8 people with even expected higher age in 2021. Our life expectancy is now 83yrs for women & 79yrs for men with advances in medical science & plenty of food availability (same time, more food is also a cause for decreased longevity) Disease can be due to genetics, aging, & environmental factors. Aging is not avoidable since it is programmed in our genes, slowed by lifestyle (eg. healthy nutrition & exercise) Eating well-balanced meals, engaging in pa, no smoking, no/moderate alcohol drink, keeping healthy body weight, adequate/regular sleeping these are lifestyle factors that under control a person"s longevity. Multiple benefits including: increase in flexibility & balance-posture & mobility. Physical activity is the most powerful predictor of mobility in later yrs. Often weakening in muscle mass slows down & increase in strength with age. Allows less likely to falls & reduces potential loss of independence.
