If you've ever wondered why your guy burps and farts and then finds it funny, here's the reason: Men don't mature until they're around 43.

By comparison, the average age at which women mature is 11 years earlier, at age 32. That's according to a new study commissioned by Nickelodeon UK to mark the launch of their new show titled Wendell & Vinnie.

Eighty per cent of the women surveyed believed that men "never stop being childish."

Breaking wind, burping and eating fast food in the early morning hours topped women's list of immature behaviour. Other signs of immaturity that women gave a thumbs-down included being passive-aggressive during arguments, being unable to cook even simple meals, and telling the same jokes over and over again.

Some 25 per cent of men described themselves as immature - nearly double the number of women who described themselves as immature. A whopping 46 per cent of women said they've been a relationship where they felt more like a mother than a partner.

On the home front, women were twice as likely as men to feel that they were the "grown up" one in their relationship, and three out of 10 women have ended a relationship with a partner due to his perceived immaturity.
