Seth Rogen explains why he doesn't want kids after reaching 40

Seth Rogen has explained why he doesn't want to have children.

Host Steven Bartlett raised the subject and Rogen was unequivocal that being childless had 'definitely' helped him to be successful.

"There's a whole huge thing I'm not doing, which is raising children," he said.

Playing devil's advocate, Bartlett asked whether he might be happier if he had kids, but Rogen was crystal clear on this too.

"I don't think it would," he replied. "I've been around a lot of children, I'm not ignorant to what it's like, I've seen everyone I know have kids. I'm 40, I know.

"Some of my friends have had kids for decades, you know. Some people want kids, some people don't want kids.

"I think a lot of people have kids before they even think about it, from what I've seen honestly. You just are told, you got through life, you get married, you have kids - it's what happens."

Rogen went on to explain that he and wife Lauren Miller Rogen - who he married in 2011 - have had discussions about kids, but over time they've become increasingly satisfied with their decision not to have any.

He continued: "Me and my wife, neither of us were like that. Honestly, the older we get the more happy and reaffirmed we are with our choice not to have kids. It was something we kind of talked about more, and we were like, 'Have we made the right choice, are we sure?'

"Now, more than anything, the conversation is like, 'Honestly, thank God we don't have children. We get to do whatever we want, we are in the prime of our lives, we are smarter than we've ever been, we understand ourselves more than we ever have, we have the capacity to achieve a level of work and a level of communication and care for one another, and a lifestyle we can live with one another that we've never been able to live before, and we can just do that and we don't have to raise a child - which the world does not need right now."
