"ow we see eyes become dim and artificial aid needed in comparative youth, and teeth drop out in mere childhood. Many men and women lose teeth before they are twenty. This simple fact is evidence enough of inherited weakness or flaw. How could a person who had lost teeth before twenty be ever said to die of old age, though he died at a hundred and ten? Death is not a supernatural event; it is an event of the most materialistic character, and may certainly be postponed, by the united efforts of the human race, to a period far more distant from the date of birth than has been the case during the historic period. The question has often been debated in my mind whether death is or is not wholly preventible; whether, if the entire human race were united in their efforts to eliminate causes of decay, death might not also be altogether eliminated."
