Yeah, because Fallout is so crucial you can't survive without it. 
When did I mention this? That he wouldn't be able to live without it? Are you trolling again surf? Bad boy...
And if you simply misinterpreted, it's a very simply concept, if you didn't eat your breakfast in the morning, you would be hungry later (work or school) and that would thus change your overall actions, mood, and mood from others for the day.
However if you ate your breakfast, (unless your just an ass hole/depressed kid/having a natural bad day) you would be much more content, and able, and in a better mood for the day.
See what I just did thar?
