Lesson 37-4 Theprocess of ageing
But these are notanalogous to what happens when man ages. A run-down watch is still a watch andcan be rewound. An old watch, by contrast, becomes so worn and unreliable thatit eventually is not worth mending. But a watch could never repair itself----itdoes not consist of living parts, only of metal, which wears away by friction. Wecould, at one time, repair ourselves----well enough, at least, to overcome allbut the most instantly fatal illnesses and accidents. Between twelve and eightyyears we gradually lose this power; an illness which at twelve would knock usover, at eighty can knock us out, and into our grave. If we could stay asvigorous as we are at twelve, it would take about 700 years for half of us todie, and another 700 for the survivors to be reduced by half again.
