Yeah, before kids and after kids should be the distinction here. Thirty doesn't change anything for anybody, it's what boring people talk about between the ages of 30 and 40 because they're uninteresting, and somehow talking about how hard it is to be "old" seems to placate other boring people. I'm 32 and it's rough ridin' great, having a baby is definitely a change though, way less time to spread around to my hobbies. BBSing definitely takes a hit.
