[Tutor] OT: Writing code while tired, counterproductive?

[Jose Amoreira]

When I get really tired, I sort of slip into an half awaken state. I still 
have my eyes open, I still look at the code, I still think about the problem, 
but suddenly the lines come alive and start arguing with each other (and some 
times arguing with me!), or setting up dates, or singing in choir, all sorts 
of crazy things. That's definitely the time to STOP!, and get some real sleep.

Cheers,
Jose Amoreira
