I had my first in my mid twenties and there wasn't a lot of bouncing back happening.

In college you can bounce back after an all nighter not just because you're younger but also because it's an opt-in single event and you can opt out of the next one when you recognize that you're sleep deprived. You can also do what my brother does and regularly sleep in till 10 to make up for the late nights.

Once you have kids there's no opt out mechanism, and sleeping in isn't an option any more. There's not really an opportunity to bounce back from the sleep loss, even for a younger adult.
