Why haven't the Sidemen grown up?

Why is the Sidemen's content still so childish?

After watching the newest video with Nick, it's hard to believe that the Sidemen are men in their 30s, most of whom are married, and 2 of which have kids. Why do they still act so childish? I swear, they seemed more mature in their early 20s than they do now. And if you say "they want to cater to kids" - fine, but then why have videos with OF models and literal pornstars in them as well? Does it not weird anyone out that one week, they do a video in public, and a bunch of kids come up to them, and the next week, we have a video filled with OF models/pornstars?

I started watching the Sidemen around 2013, and I'm around the same age as them, for context. Tbh, they're starting to become really grating. But I know they're not like normally - the Josh from ZerkaaCards is way different to how Josh acts in the main videos, for example. I don't get why they don't want their content to mature.
