In our case we hope to (loosely) apply Albert Einstein's theory of special relativity E = mc 2,
Enjoyment = Montana Times the Speed of Life Squared,
as in all "special relativity" cases you may meet some Quantum Mechanics that will create the need for the Uncertainty Principle.
We also like the DQDick theory "I'm hoping our current rigs lifespan is somewhat equal to my own."
Merry Christmas, and Happy New Year.
