NUS researchers found that young women who are impatient have cells that show signs of more rapid ageing
For young women seeking longevity and youth, a little patience may help you live longer. A group of researchers from the National University of Singapore (NUS) has found that the cells of impatient young women are ageing faster than their more patient peers, as characterised by shorter leukocyte telomeres. This novel study is the first to link a fundamental determinant of decision making such as impatience to a molecular marker for cellular ageing in humans.
Led by Professor Richard Ebstein from the Department of Psychology and Professor Chew Soo Hong from the Department of Economics at the NUS Faculty of Arts and Social Sciences, the NUS research team investigated the possible long-term health consequences of patience in a large group of 1,158 young, healthy undergraduates at NUS.
The team first employed a behavioural economic game to determine participants’ degree of impatience in going for immediate payoff rather than receiving a little more a month later. To evaluate the health implications of this personality trait elicited in a controlled laboratory setting, the team then measured the participants’ telomere length – telomeres are the caps at the end of each strand of DNA that protect the chromosomes, decreasing in length each time a cell divides and ages. The team found that female individuals who were identified as impatient had shorter telomere length, indicating that they are ageing faster at the cellular level.
Their findings were recently published in Proceedings of the National Academy of Sciences (USA) on 22 February 2016.
