According to a study reported today, November 19, 2007 on Health Day, men who had 4 children before they were 30 have a 61% greater chance of living to 100 than men without this history. I had 5 children before I was 30 and 8 children before I was 40 and 9 children before I was 43. So I ought to live to be 200, right?
Here is a small part of what the HealtDay article on Yahoo news says:
Some surprising findings emerged. First of all, a man's chances of reaching 100 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.
That's at odds with a prevailing theory in longevity research that holds that "there is a trade-off between the number of children and [parental] longevity," noted Arnold Mitnitski, a longevity researcher and associate professor of medicine, mathematics and statistics at Dalhousie University in Halifax, Canada.
