Why would anyone ever turn off their computer ?

• During the winter my computer doubles as an extra adiator.
• Cooling fans generate white noise, which helps me get to sleep.
• Who has time for boot sequences?
• As long as the computer is running, it's not broken.
• Computer doubles as a power failure notification device.
• My penis grows 1mm every 5 days of uptime.
• Can claim CPU cycles donated to SETI@home, folding@home et al, as charitable donations on my income taxes.
• Somebody might say something important on IRC.
• Too difficult to find power switch with eye crust.
• When computer is off, it is no longer protected by the firewall.
