birthday paradox or pigeon-hole principle

The Pope celebrated his birthday today with an appropriately Bavarian entourage of well-wishers bringing some characteristically German traditions to Rome. He was treated to quite a few performances from this delegation. The Pope, the first German to hold the office in over a thousand years, shares his birth date with another, though perhaps less famous, German citizen, hailing from Erfurt, the city where Martin Luther was ordained and the Pope visited last September: Germany’s first test-tube baby (sogennante Retortenbabies, which sounds especially cruel, although test-tube is bad enough, as if they were sea-monkeys or kangaroo-joeys).

No details were disclosed on that young adult born in 1982 spent his birthday. I wonder what these two Aries would think of one another. The star or the conditions that one is born under of course is not everything, and the birthday problem refers to the very human propensity to make something out of a not so unlikely coincidence, whereas it would be more statistically remarkable if a randomly assembled and relatively small group did not have a few individuals that shared the same birthday. Still, I wonder what these two might have in common and what they might learn from one another.
