Amazingly, I got all of my shopping done early. Thank you Bezos, Amazon is a timesaver/energy economizer; after all, E=mc^2 is also the formula describing the expansion of the universe, id est, time. Especially useful for out of town family, when time is a palpable constraint. Fundamentally, I am a Lazy Middle-class Intellectual; id est, I like force multipliers that reduce the energetic requirements to do something. Enjoy synergies and getting the biggest bang for the energy that I allocate to a task.
