Input:
------

  The program asks for two dates.  Key in any date you wish for both inputs.
NORMALLY, one would key in the desired BIRTHDATE for the beginning date and
the CURRENT DATE for the ending date.  The program simply calculates the
delta-days between these dates to get the "number of days the user has been
alive."

The Calculation:
----------------

  Biorythm theory I'm aware of is:

    a> Take the # of days alive.

       1. Take # MOD 23 for Physical cycle (23 days long)
       2. Take # MOD 28 for Emotional cycle (28 days long)
       3. Take # MOD 33 for Intellectual cycle (33 days long)

    b> These #'s are listed on the graph at 90ø, 180ø and 270ø as P, E, and
       I.  These numbers correspond to the current phase.

Output:
-------

  The graph is a 360ø sine-wave.  Since the "cycles" are of different phases,
a line intersects the sine-wave at the corresponding calculated point offset
of where the indicated cycle would be if that particular cycle was the only
cycle plotted and the graph was scaled accordingly. That is, the 360ø
sine-wave would be 100% at 360ø for 23 days, for physical, 100% at 360ø for
28 days, emotional, and 100% at 360ø, intellectual.  The intersection point
is an accurate approximation of what each cycle looks like "graphically."
That is, if the "physical" cycle is intersecting the graph at 0-90ø, then
your current physical strength is positive and increasing.  If the physical
cycle is intersecting at 90-180ø, then your physical cycle is positive and
decreasing.  Follow the same rules for the other two cycles.

To end the program:
-------------------

  When the system asks for the dates, press "ENTER" twice.  Also, pressing
ENTER to any of the date prompts uses the system date of the calculator.  So,
to simplify things, enter the BIRTHDATE for the beginning date, and press
ENTER for the ending date.  The system date is automatically used.
