One of the first things I learned as a young soldier is that the army would provide all the discomfort neccessary. There was no reason for you to add to this yourself.
Words to live by for those of you who are still young enough to be "in the game".
Never stand when you can sit,and never sit when you can lay down. Never run when you can walk,and never walk when you can ride. Never be awake when you can be sleeping. Never refuse to eat when you have the chance because there is no telling when you will get this chance again. The army/USMC will provide you with all the exahustion,hunger,and discomfort you will ever need.

LOL! If the SF dining hall was army 'discomfort', what was comfort?
