The Height and Weight fields are output quantities
only-the values cannot be changed directly. The values are constantly
updated as the model changes. Age alone determines the height.
In addition to age and extra fat, the weight is affected by the
inclusion of organs. The densities of the skeleton and lungs
are different than soft tissue; those densities are used only
if the organ is explicitly included. The external breasts and
male genitalia contribute to the weight.
The Units submenu on the main menu gives alternatives for
the choice of measure.
