I suspect many of us older coders don't pull all-nighters because 1. We've not left critical codding to the last minute. 2. If critical coding is not completed, you realize doing it at the last minute usually means crap-code. 3. Code produced at 3:00AM after 8 cups of coffee is usually crap code. 4. Good Project Management skills either learned formally or over 20-30 years means the team has created a good WBS so you are not coding at 3:00AM. 5. All nighters usually mean something is being done wrong. Geezer-Geeks know that. Coding is a marathon, not a series of crazed sprints. Nuff said for now.
