I've done a few all-nighters in my 30s and 40s, and they generally feel the same as my 20s. Still get that clear headed, high focus second wind around 4am that carries through until noon or so.

But, I definitely crash harder than I did in my 20s and need longer to recover after. In my 20s, would be fine if the next night was a normal one, now it takes multiple days.

It's definitely something I try to avoid at this age, as opposed to just being standard procedure back in college.
