Apparently there are periods in life when those in relationships are most likely to stray.
Researchers from infidelity websitehave revealed that we're more than twice as likely to cheat at the age of 39. Other 'danger ages' are 29 and 49 – in other words, the years when we're about to enter a new decade.
But why is this? CBS news reports that a 2014 study by researchers Adam L. Alter and Hal E. Hershfield at New York University and the University of California, Los Angeles, respectively, found there were 18 per cent more men with 9-ending ages on extramarital affairs websites.
They found that people about to enter their next decade were more preoccupied with ageing and whether their lives were 'meaningful', which could lead to 'a search for, or crisis of meaning,' such as having an affair.
In other words, these are the ages we're most likely to experience a personal crisis – which cheating goes hand-in-hand with.
Other danger factors include low morality, high risk-taking behaviour and whether we're in an environment that presents opportunity for cheating.
