the body can survive for 8 to 21 days without food and water and up to two months if there's access to an adequate water intake. (Google it)The lack of logistics makes it near impossible to even get far enough to get situated for survival starting from scratch.

Love the concept but definitely need some changes such as food and water intake water intake as stated.
