Five hundred and sixteen adult subjects were divided into three groups—172 dentists, their 172 wives and 172 other women aged‐paired to the wives—who were studied in terms of similarities in their hemoglobin levels. The data reveal a statistically significant coefficient of correlation (r= +0.317) only in the married couples. This together with a higher correlation in the older (r=+0.347) versus the younger (r=+0.275) couples indicates the possible influence of environmental forces. It is concluded that husbands and wives become alike chemically largely because they have similar social (alcohol, tobacco), dietary, sleeping and exercise habits and are subjected to similar psychic stresses.
