Nature has a job to do. It does its job by the method that seems most suited to each individual whom its powers have created. It has made this one susceptible to heart disease and that one to stroke and yet another to cancer, some after a long time on this earth and some after a time much too brief, at least by our own reckoning. The animal economy has formed the circumstances by which each generation is to be succeeded by the next. Against the relentless forces and cycles of nature there can be no lasting victory.
