| We all age at different rates.
Heredity clearly plays an important part. But recent research studies by
gerontologists indicate that life-style may be equally significant in
determining who will remain youthful. As a rule, single men and women have shorter lives than married men and women. Studies show that those who have been widowed, especially men, have a longer life expectancy if they remarry soon. Both men and women seem to have a greater resistance to disease and death when their marriage is undamaged. According to a 1960 study, women who have borne three children have the lowest mortality rates. Those who have borne four or more have the highest. Childless women and those with only one child generally don’t live as long as mother of two or three, according to University of Chicago sociologists Evenly M. Kitagawa and A.
