Author and philosopher Ilchi Lee believes that we will finally reach true world peace when individuals begin loving one another, even total strangers, as if they were family.

A new study conducted at the University of Missouri reveals that close friends can be just as caring and thoughtful when taking care of the elderly as the senior's own family. They noted that their findings are significant in light of an aging population and a growing prevalence of non-traditional families.

"The idea that family obligations are based on genetic ties is not true for most Americans," said researcher Lawrence Ganong, Ph.D.

Authors of the study found that the strength of a relationship and history of mutual kindness mattered more than an immediate familial link when it came to choosing a person to care for a senior member of the family.

Results of this study suggest that world peace day may be right around the corner. The findings may also provide life dreams and hope for older people facing an assisted living situation.
