Life expectancy affects major decisions
The major decisions people make throughout their life could be affected by how long they expect to live. A new study from Queen's University found matters relating to marriage, divorce, parenthood and abortion might all be subconsciously impacted in this regard.
According to the investigation, people are likely to invest more in education if they believe they will be around for many years to come, while others might choose to wed and have children at an earlier stage should they predict a shorter life span.
Moreover, the findings - which have been published online by the Archives of Sexual Behaviour - suggested couples forecasting an earlier death may be more inclined to try and make the relationship work rather than seek a divorce.
Daniel Krupp, Post Doctoral Fellow in the mathematics department at Queens - which is located in Canada and was established in 1841 - stated: "Life expectancy might be driving all of these major decisions."
Anita Abrams, Chartered Psychologist, commented: "It is hard to disagree with Dr Johnson's view that awareness of impending mortality tends to concentrate the mind wonderfully.
"Some of us will defiantly live in the present and gather rosebuds while we may - and know very well why we do so.
"Not all of us, however, will respond prudently. Not all of us will be conscious of what drives our decision-making.
"Perhaps those older men, who start a new family with a younger (second) wife, do so to defy mortality by repeating their youth."
