I like that story because my kid has such a birthday that will make us have to decide. But it is a bit annoying that now there are conflicting statements: some research seems to claim the disadvantage of being the younger kid is statistically significant throughout the whole life (or at least university, not sure about jobs), and now this which claims the opposite. I guess they cancel each other out. Perhaps it is best to not think about it at all and just let things run their "natural" course, and leave it to the kid to deal with whatever the world throws at him :-/
