I'm geared up for local hiking and carry enough to last me until help arrives if I'm hurt. From what I've read, 72 hours is a good starting point to plan for. Primarily water, fire starting , shelter materials and a little food. Based on proper planning prior to heading out. If I didn't return at a given time, it will take a while for others to locate me given the worst case scenario. If I fell and suffered a major mechanical breakage to my body and couldn't move. I'd have to maintain until help arrived. If I survived some type of crash or boat wreck, maybe even getting stranded due to other unseen circumstances but was still in good physical condition, I'd last much longer, probably months as long as I was able to acquire food. Others brought up a good point pertaining to wilderness nutrition, looks like I have some research to do! My survival experience was learned mostly through the military in Panama. Jungle survival, I feel is much easier than surviving in the mountains or forested areas where winter climates come into play. The jungle is a virtual smorgasbord when it comes to food. Plenty of shelter making materials and water supplies.
