The NewScientist article How to live long and prosper said

WANT to be the first one on your block to live to 100? You are in with a fighting chance if you’re the first-born child of a young mother.
 
Natalia Gavrilova and Leonid Gavrilov of the University of Chicago sifted through data gathered on 991 centenarians born in the US between 1875 and 1899 and used US census and Social Security Administration records to reconstruct the family histories of 198 of them, searching for anything they had in common.
 
It turned out that first-born children were 1.7 times as likely as their siblings to live to be 100. An even stronger predictor of longevity was how young their mother was when they were born. Those whose mothers were less than 25 years old were twice as likely to survive beyond a century.
