L01: Discuss physical development in late adulthood
Physical development: In 1900, only 1 person in 25 was over the age of 65. Today, that
figure has more than tripled, to 1 in 8 of us. By mid-century, more than 1 in 5 North
Americans will be 65 or older. By 2050, we expect the percentage of North Americans
over the age of 75 will have doubled. To put these numbers in historical context,
consider that through virtually all of human history, until the beginning of the 19th
century, only a small fraction of humans lived to the age of 50.
Longevity and life expectancy
Life span or longevity – length of time one can live under the best circumstances;
depends on genetics and environment; people can live to 115.
Life expectancy – number of years a person in a given population group can
expect to live
oEuropean American 100 years ago born in USA – 47 years
oAfrican American – 35.5 years
Life expectancy in the past – german measles, smallpox, diphtheria –
controlled/eradicated now; water supplies, diet, health care
Longevity gap between genders is narrowing; gap exists because women have
estrogen that offers some protection against heart disease; men likely to die of
accidents, cirrhosis, strokes, homicide, suicide, AIDS, cancer – more unhealthy
Men are more reluctant o visit doctors and talk about health concerns
