SAN FRANCISCO — Got milk? If you do, take a moment to ponder the true oddness of being able to drink milk after you're a baby.
No other species but humans can. And most humans can't either.

..."It's not normal. Somewhat less than 40% of people in the world retain the ability to digest lactose after childhood. The numbers are often given as close to 0% of Native Americans, 5% of Asians, 25% of African and Caribbean peoples, 50% of Mediterranean peoples and 90% of northern Europeans. Sweden has one of the world's highest percentages of lactase tolerant people."
