NOTES:
• The volumetric integral of the function defined by the loop repre-sents the maximum amount of life that CY-1 can have, including joy and pain.
• A looped life is conventionally defined as one in which the time trav-eler necessarily suspends his own memory in order to continue on.
• The actual length of ABC may be significantly different from the subjective psychological duration experienced by a past-oriented traveler within the loop, e.g., it might feel like a month, but only be a moment.
