Look at the cheetah. It is one of the fastest creatures on earth. Yet it waits patiently for the opportunity to strike. It is fast and furious, yet it waits in cold calculating contemplation. If it ran all the time, it would wear itself out. If it never ran at all, its muscles would waste away.
This is the problem with philosophical questions: they rarely reflect real world physics. In trying to simplify life, hypothetical questions eliminate the very thing that makes life what it is.
