2. Characteristic of our Dataset Over 16,000 persons belonging to the European aristocracy 1800-1880 extinct birth cohorts Adult persons aged 30+ Data extracted from the professional genealogical data sources including Genealogisches Handbook des Adels, Almanac de Gotha, Burke Peerage and Baronetage.

3. Season of Birth and Female Lifespan 8,284 females from European aristocratic families born in 1800-1880 Seasonal Differences in Adult Lifespan at Age 30 Life expectancy of adult women (30+) as a function of month of birth (expressed as a difference from the reference level for those born in February). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multivariate regression with categorized nominal variables.

4. Season of Birth and Female Lifespan 6,517 females from European aristocratic families born in 1800-1880 Seasonal Differences in Adult Lifespan at Age 60 Life expectancy of adult women (60+) as a function of month of birth (expressed as a difference from the reference level for those born in February). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multivariate regression with categorized nominal variables.

5. Models Used in the Season-of-Birth Analyses Multiple linear regression models with nominal variables Multilevel linear regression models (with family as a second level) Proportional hazard models with stratification

6. Life expectancy of adult women (30+) as a function of year of birth Mean Lifespan of Females Born in December and February as a Function of Birth Year

7. Season of Birth and Female Lifespan 7,020 Mennonite females born in 1800-1890 Seasonal Differences in Adult Lifespan at Age 30 Life expectancy of adult women (30+) as a function of month of birth (expressed as a difference from the reference level for those born in February). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multivariate regression with categorized nominal variables.

8. Season of Birth and Male Lifespan 8,187 Mennonite males born in 1800-1890 Seasonal Differences in Adult Lifespan at Age 30 Life expectancy of adult men (30+) as a function of month of birth (expressed as a difference from the reference level for those born in February). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multivariate regression with categorized nominal variables.

9. Season-of-Birth Effects Found in Other Studies Female childlessness (born in January, July) – Smits et al., 1997. Schizoprenia is more frequent for persons born in February (Dassa et al., 1996) and this effect is more expressed among females

10. Molecular Effects on Ageing New Ideas and Findings by Bruce Ames: The rate of mutation damage is NOT immutable, but it can be dramatically decreased by very simple measures: -- Through elimination of deficiencies in vitamins and other micronutrients (iron, zinc, magnesium, etc). Micronutrient deficiencies are very common even in the modern wealthy populations These deficiencies are much more important than radiation, industrial pollution and most other hazards Our hypothesis: Remarkable improvement in the oldest-old survival may reflect an unintended retardation of the aging process, caused by decreased damage accumulation, because of improving the micronutrient status in recent decades

11. Molecular Effects on Ageing (2) Ideas and Findings by Bruce Ames: The rate of damage accumulation is NOT immutable, but it can be dramatically decreased by PREVENTING INFLAMMATION: Inflammation causes tissue damage through many mechanisms including production of Hypochlorous acid (HOCl), which produces DNA damage (through incorporation of chlorinated nucleosides). Chronic inflammation may contribute to many age-related degenerative diseases including cancer Hypothesis: Remarkable improvement in the oldest-old survival may reflect an unintended retardation of the aging process, caused by decreased damage accumulation, because of partial PREVENTION of INFLAMMATION through better control over infectious diseases in recent decades

13. Daughters' Lifespan (30+) as a Function of Paternal Age at Daughter's Birth 6,032 daughters from European aristocratic families born in 1800-1880 Life expectancy of adult women (30+) as a function of father's age when these women were born (expressed as a difference from the reference level for those born to fathers of 40-44 years). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multiple regression with nominal variables. Daughters of parents who survived to 50 years.

14. Daughters' Lifespan (60+) as a Function of Paternal Age at Daughter's Birth 4,832 daughters from European aristocratic families born in 1800-1880 Life expectancy of older women (60+) as a function of father's age when these women were born (expressed as a difference from the reference level for those born to fathers of 40-44 years). The data are point estimates (with standard errors) of the differential intercept coefficients adjusted for other explanatory variables using multiple regression with nominal variables. Daughters of parents who survived to 50 years.
