% Problem  : Conditions for a constant then increasing hazard of mortality
% Version  : [Han98] axioms.
% English  : In a drifting environment, an endowed organization's hazard of
%            mortality is constant during the period of immunity; beyond the
%            period of immunity, the hazard rises with age.
