A new study has found that cheating is more common at certain ages.
Conducted by IllicitEncounters.com, the research showed that the age where most affairs took place was 39 years of age.
The website found that people with ages ending in 9 are the most likely to cheat: 19, 29, 49 and 59.
The researchers inferred that this was because these ages represent a turning point in people's lives.
Other findings included that people are more likely to cheat to get their partner's attention or as payback.
