Also the aim at high sodium is for electrolyte replacement in high activity or high exertion labor that comes after a disaster or military related movements... just like the MREs have high sodium content. But such as some who are allergic to milk or eggs, sodium can do some in.... While reading "One second after" a noticed something that was mentioned in the book a half dozen times.... the increased number of deaths caused by some poeple actually being exposed "TO" physical labor. The book comments on a a dozen people who dies just walking down the freeway after the EMP strike. Everyday I go to work (Engineering firm) the more I keep seeing this passage from his book flash across my eyes. There are a few dozen guys and girls who were issued handicap plates just because they COULD NOT walk the increased distance from the standard parking lot. I think this is ass backwards. One lady in particular totes one of those carry on wheeled duffle thing (like you see in the overhead compartments in a aircraft) full of food to snack on for the day. Ive seen her open it to get diet coke and chee-tos and about fell over.
