  We collect and analyze the data for working time, life expectancy, and the
pair output and infrastructure of industrializing nations. During S-functional
recovery from disaster the pair's time shifts yield 25 years for the
infrastructure's physical lifetime. At G7 level the per capita outputs converge
and the time shifts identify a heritable quantity with a reaction time of 62
years. It seems to control demand and the spare time required for enjoying G7
affluence. The sum of spare and working time is fixed by the universal flow of
time. This yields analytic solutions for equilibrium, recovery, and long-term
evolution for all six variables with biologically stabilized parameters.
