Life Expectancy Controls Major Life Decisions


Life Expectancy Controls Major Life Decisions

(ePharmaNews) - A new Canadian study has found that major decisions in life is affected by how long people believe they will live.

 

This study, which was published online yesterday 9 April  in Archives of Sexual Behaviour, professor Daniel Krupp from Queen’s University has reviewed population data from Statistics Canada to find out if Major life decisions such as marriage, divorce, abortion, having a child and attending university are  subconsciously influenced by life expectancy.
"Life expectancy might be driving all of these major decisions," says Daniel Krupp, a post doctoral fellow in the Queen's math department who has a background in psychology and biology.
 
The longer someone expects to live, the more time they will invest in education. If life expectancy is short, someone may decide to get married and have children sooner, or stick with the partner they are currently with rather than seek a divorce.
It is impossible to know how long someone is going to live; but there are many life expectancy cues not consciously processed, affecting how many more years people expect to live. How healthy are they? Do they have a risky job? Are their grandparents still alive? Is there a history of disease in the family?
 
A branch of evolutionary theory known as life history theory predicts life expectancy to influence major life decisions in humans, as it does in the lives of other animals.
 
Dr.Krupp hasn't found any differences between men and women in this study, and he pointed out that an increase in life expectancy - due to improvements in health care and increase in mean age- will lead to a continued increase in the ages of marriage and reproduction, however, getting married and starting a family can't wait forever, so it is also possible that these effects will weaken beyond a certain point.
