Although much research is done into diseases and illnesses, expat insurance customers could benefit from studies into healthiness.
Political studies professor Colin Farelly in Canada's Queen's University recommended that researchers look into "positive biology" as much as they examine health complaints.
He encouraged scientists to look into "the causes of health and happiness", noting many individuals reach the age of 100 without suffering from any diseases.
This approach to research could result in "significant medical breakthroughs", the professor predicted.
His research papers, including a recent document urging analysis of the biological basis for aging, are part of an ongoing book project and have been published in the European Molecular Biology Organisation's Reports and Journals of Gerontology.
Perhaps issues such as how diseases are caused are not the most important healthcare problems to resolve, Professor Farelly stated.
In his blog, he argued biological aging is humanity's biggest health threat, as it causes a variety of ailments including strokes, hearing loss, cancer, heart disease and joint pain.
