I don't even keep MRE's for one major reason. If you have ever had to eat them for an extended period of time, say more than 4 or 5 days on an exclusive basis you would realize the tremendous amount of water required to even pass them out the other side. I don't want to waste my water trying to digest MRE's. I'm telling you bowell movements are downright painful. You basically give birth to a fist size turd that scrapes you all the way out. Upside is you really don't even need toilet paper.
