If you ask me, the desire to utilize 100% of all computing resources just because you have them is not a good behavior.
I too once also had this desire. I just wanted to see torrents transferring and CPU churning.. even if it was on something like tormenting which really isn't beneficial for anyone.
Now I'm proud to say that If I don't need my laptop to complete a task, then it's shut. We'll now I'm doing scientific computing at the University, and I can't get enough computing power!!!
even then I could spend more time refining my algorithms and less time watching the CPU Temp Monitor

lol. Though it's quite ascetic to watch the CPU temperature rise
I'm sure it wouldn't hurt to shut all the computers off and read for a few more days.
