Fuel econonmy, in context with aviation, should not end with a (?).
Complex chores, emotional distractions, boring (if not hypnotic)
seat-warming, unpredictable winds, unpredictable landscape for
touching down; especially at night. Fuel economy could too easily be
life or death, or a major inconvenience. All part of the adventure of
flight. The 'red box', then, doesn't look so threatening, but
intimate knowledge of one's aircraft. It is control of substance.

Don't most GA pilots routinely take off with full tanks, anyway?
