Well, I just have one more thing to say in this thread, and then I'm done with it.

The longest I have ever gone without any food whatsoever was 72 hours. I was not in a survival situation. I was just testing myself. I do physical labor for a living. So during those 72 hours I did 24 hours of labor (8 hours a day).

I was completely worn out.

So let's imagine that it's been a week since I last ate. I've been working hard the entire week. I had to build a shelter. I had to collect firewood regularly. I had to search for water. And I've been putting a lot of effort into trying to get some food. Luckily for me the weather has been perfect so my life has been easy in that regard (god help me if I was both starving and freezing).

At that point my body is screaming, and no doubt my mental state is slipping somewhat. That's a BAD situation to be in. I don't give a damn what anyone says in their survival book. As far as I'm concerned, food is just as important as water.
