I think it's all about being able to focus the hunger into whatever you need to do - I just can't do it when I know the food is right there - my brain simply knows I'm not working towards getting food and it's very distracting.

It's different than when I'm in the field - I know I'll eat when I finish the job, so I just focus all I've got into doing the work faster.
