Clearing out the fog that settles in over time. If you were to leave your
system up and running 24/7 for weeks on end, you're bound to have a crash at
some point. If you're lucky, it won't happen at a critical time, but if
you're not, no knowing what you may lose. Rebooting once in awhile just
makes sense and it's not like it takes forever. Reboot when you're taking a
nature break.
