30 Something Baby Doc

My Current Demographics: 37 years old; Single: No Children

Recent Excellent Retrospective study: A man's chances of reaching 100 years of age rose along with the number of children he had produced by age 30.

Compared to childless men of the same age, a 30-year-old man in 1917 who had one to three children had a 61 percent increased chance of living past a century, the data showed. However, a man's chances for extreme longevity almost tripled if he had fathered four or more children by age 30, the study found.

Fortunately for me : Other characteristics -- including marital and immigration status at 30 -- had little or no impact on longevity.
Finally, taller men were only marginally more likely to live to 100 than their shorter peers, the team found.
