A separate issue is that while I agree on the correlatii of talents and ability/circumstances to nuture it, extreme performance also requires practice - a finite resource. > a great, healthy childhood will augment all these I would put it that poor developmental conditions (from gestation on) prevent realization of genetic potential, rather than great ones "augment", because it just has to be adequate. A so-called "hygiene factor". Nutrition, stability - that sort of thing.
