Late Adulthood Late adulthood is known as the period of life after middle adulthood, usually from around 65 years old to death (Santrock, 2013, p. 485). There are many varying stages of development and health in late adulthood, along with steady changing of life expectancy. Aging is a part of life, and with it comes changes in every area of living. Many diseases find late adulthood as an opportune time to affect people. Eventually, whether caused by disease or another reason, every individual dies. Death is unique to every person, and healthcare in America is changing to reflect that. This stage of life is a time when bodily processes and functions may be decreasing, but depending on lifestyle choices, death can come at different times. …show more content…
The way God created us as humans is a life cycle where eventually late adulthood comes with the biology of aging. Santrock (2013) describes five different theories of why humans age (p. 541). The evolutionary theory explains that aging is more of a natural selection process, and diseases occur in the elderly because they “would have been eliminated” if they were in younger people (Santrock, 2013, p.541). Cellular clock theory describes how cells get tired of dividing after they have been reproducing for so long (Santrock, 2013, p.541). Free-radical theory explains when “cells metabolize energy the by-products include unstable oxygen molecules known as free radicals” (Santrock, 2013, p.541). The unstable oxygen molecules can damage DNA and other structures inside the cell (Santrock, 2013, p.541). Mitochondrial theory describes how aging occurs because of the mitochondria essentially wearing out and becoming less efficient (Santrock, 2013, p.542). Mitochondria are the cell’s “power house,” and they convert energy inside the cell (Bailey, 2008). The last theory, hormonal stress theory, illustrates the effects of stress, especially long term stress, on aging (Santrock, 2013, p.542). Stress released hormones which depress the immune system making people more susceptible to disease (Santrock, 2013, p.542). There are many theories about why human’s age, and all of them may be true, but regardless aging is inevitable and so are its effects.
