In order to save the human race from mental illness and other social ills, Dr. Kellogg advocated the use of eugenics and euthenics, and he also advocated the use of a eugenics registry in order to keep the “races pure.”
Because of the society is coming more and more modern, the defects of the trade crackers are very extrude: pollute the euthenics, wasteful, and so on.
A study of these long-lived families from another point of view will reveal that heredity is the primary factor and that good environment, euthenics, is the secondary one.
But this illustration certainly gives no ground for a belief that euthenics is sufficient to prolong one's life _beyond_ the inherited limit.
In so far, then, as euthenics is actually providing man with more favorable surroundings, -- not with ostensibly more favorable surroundings which, in reality, are unfavorable -- there can be no antagonism between it and eugenics.
He may fancy that the early death of a parent left the child without sufficient care, and that neglect, poverty, or some other factor of euthenics brought about the child's death.
In general, euthenics, when not accompanied by some form of selection
 The entire field of race betterment and social improvement is divided between _eugenics_, which considers only germinal or heritable changes in the race; and _euthenics_, which deals with improvement in the individual, and in his environment.
If they had had more euthenics, they should have lived longer.
There is no short-cut by way of euthenics, merely.
