Why not? Having kids isn't a death sentence, you're still a person. If you organize your life well and have a good balance, no need to go to one extreme or another. Sometimes some of y'all really sound like you have a binary "or/or" way of thinking. Nuance and moderation are your friends.
I have this friend who's 36 and his kids are already 10 and 8 years old I think, dude never stopped partying, going to drinks, movies, exhibitions, sports, he works, his wife is the same, they just know how to organize their life in a way they can do a little bit of everything while still spending the vast majority of their time with their kids.
