In the two previous articles of this series, “Quebec mortality rate under the French regime” and “The first French-Canadian centenarians in Quebec“, we successively mentioned the high mortality which afflicted our ancestors at all ages of life and the scarcity of people reaching extreme ages. Today, we will present some factors underlying these realities.
Deaths of Native-born French-Canadians at age 97 and older which occurred before 1850
|SEX||Year of birth||Year of death||Age at death|
|Men: 8 ; Women: 23|
Thirty-one people accomplished the feat, twenty-three women and eight men. Why such an imbalance in favor of women, when their life expectancy at age 25 is 2.5 years less than that of men?
It is that beyond the reproductive period, when mothers were at a significant risk of dying in childbirth, women have a survival advantage over their partners. We know that part of this benefit is biological because male mortality is higher than female mortality from the very beginning of life, including in-utero. This genetic difference is especially associated with a better resistance of women to biological aging, as well as an hormonal advantage.
Indeed, for example, estrogen facilitates the elimination of bad cholesterol and thus reduces the risk of heart problems; testosterone, on the other hand, is associated with violence and risk taking.
That said, regardless of sex, why do some individuals reach higher ages than their contemporaries? While we know that there is more to it than chance, no explanation of this reality is currently unanimous. The study of extreme cases of longevity does not really reveal much: the “little glasses of gin before dinner” and other recipes of the kind have no serious basis.
It is tempting to believe, however, that some individuals initially have an advantage over others; Is it not said that the best chance of living old is to have parents and grandparents who have themselves reached an old age?
In this regard, I submit to you the extraordinary family of Nicolas Lizotte and Marie-Madeliene Miville-Deschênes, who married on May 3, 1724 in La Pocatière. Out of the 5 French Canadians who became centenarians before 1850, two of them were born of this couple, and one of their sisters is also part of our above-mentioned list, since she died at 98 years of age!
And it doesn’t stop there! The father, Nicolas Lizotte, died at 98 years old, making him the second oldest French Canadian male who died before 1850. I don’t know about you, but I wouldn’t mind being a Lizotte right now!
