nice article.. an eye opener a few queries... was this survey done on people of same age( i.e when both the younger and elder ones attain the same age..?).. else can it be termed as accurate?? did it cover all strata of the society?? "The New York Times points out that among other tangential indices, firstborns have won more Nobel Prizes in science than younger siblings". -In a family, if the elder one chooses a particular profession say science as quoted in this article.. the parents might guide the younger one into opting for a different stream..!
