Problem

After three days without food you die on the spot, and after three days
without sleep you die on the spot.  Bob has neither eaten nor slept for
three days and is at the end of the period.  If he eats he will die of
lack of sleep; if he sleeps he will die of lack of food.  What should he
do?

Show solution

He has to eat and sleep simultaneously.  No big deal, since he must have
done that three days ago.
