There are those of us that aren't in the best of health but still like to camp, hike, or just get out. But what if a situation arises that we get lost, injured, or for whatever reason have to survive? What if we can't carry a lot? What are some essentials that we should think about carrying that won't overload our weight limit? For example: What to pack in a first aid kit What knife to bring Specific foods (dependant on health, like for diabetics) Extra clothing (season dependant) Etc.... For me, I have type 2 diabetes and heart disease and I have stints (if that matters). Are there any good books or readings for such things?
