Larry,

If you neglect to eat, drink, etc. you are at risk of beginning to
loose your ability to focus on all those other tasks you are talking
about. Most people need food every 2 to 4 hours to maintain peak
concentration and we have all seen the effects of dehydration too many
times. I have lost at least one friend to that here in the west.

That is why most of us find food that we can eat with little effort. I
tend to use soft granola bars (the hard ones dehydrate me and are
messy), I like apples because they tend to settle my stomach and
provide moisture as well.
