This is why an incandescent lightbulb is much more likely to fail when 
you turn it on than at any other time.  I've read stories about bulbs 
that have been working for decades because they've never been turned 
off.  I have two reasons for leaving my desktop on 24/7: first, because 
Linux is designed to be run that way[1] and that allows me to use my 
uptime[2] as an example of how stable Linux is and second, I have BOINC 
installed and even when I'm away at a convention, or house sitting, it's 
doing useful work.
