Good point on over-use of laxatives-tends to destroy intestinal muscle tone and thus become a self-perpetuating problem. I offer the enema option as an alternative to reliance on pharmaceuticals. Based upon the low-fiber survival rations that seem most popular-chocolate candy, energy bars, mainstay products, protein supplement drinks-some of the ETS population is at extreme risk of constipation during a survival scenario. This is not an issue in the 72 hour envelope, but eventually, the gates will have to be re-opened or the survivors will be detonating like human grenades from the accumulated biologic pressure. Not a pretty picture.Best to plan for it.
