A study into the differences in maturity between genders revealed both men and women agree men remain 'immature' well into their late 30s and early 40s.
But the average age at which women mature emerged as 32.
Alarmingly, eight out of ten women believe that men 'never stop being childish' - with breaking wind, burping, eating fast food in the early hours and playing videogames their biggest bug-bears.
Staying silent during arguments, not being able to cook simple meals and re-telling the same old jokes and stories when with the lads were also hailed as signs of immaturity.
The research was commissioned by Nickelodeon UK to mark the launch of the new show Wendell & Vinnie showing weeknights at 7:00pm.
