Presumed

I don't think starvation is the only objective in food procurement. Replacing minerals/sugars/vitamins etc is also a priority. After hiking all day without a proper meal, my mom got really sick due to hypoglyceamia. (sorry, spelling might be wrong). There were other complications (hypothermia, mental stress, fatigue, and a weight of 45kg), most of which might be present even in a short term survival situation.

I agree when you say <<I wouldn't dream of dictating what anyone else includes in their kit>>, but I belive that you need to try cater for a diverse range of situations. And, your PSK might not always be just for you.
