What was the longest time spent in front of your PC?

I have spent more than 15 hours a day working in front of my computer, many times.

lol, I was working more than half day in front of my computer when doing programing.

I've spent days on my machine, not turning it off, sleeping on the floor, eating while I worked. I have done this several times, not lately though. I must have been enthusiastic about something, ah yes, I remember, I was waiting for sats to collect the telemetry, and doing some coding for a bit of software I was writing. It is nice to see others get the keyboard marks on the face sometimes as well.

i stood one time almost for 24 hours , i just talked on mirc, i didn`t do anything interesting , like i said i just lost the time, by the time when i wanted to go to sleep, i looked in the mirror and i had some tired eyes, i was scared of me , after that i went in bed to sleep, i slept for about 20 hours , when i woke up i felt like the world is going round and round , almost like i was drunk :)

I spent once 16 hours, playing MU online, you have to stay hours to have a RR there.

well mine was around 20 hours continusly i was working on my design project. http://bash.reallifelog.com
