Healthy in High School

Has anyone else noticed how much healthier high school students look compared to the rest of the japanese? The girls actually have some meat on their bones and the boys and girls who play sports often have a, god forbid, tan. I recently saw some of my old students who have graduated and the girls look like stick figures.

Have you seen those stick figure ladies? It looks like their little handbag will break their arm. And they can have kids?

Our apartment block is a baby factory, I think there are fertility drugs in the water. Anyway, it has given me ample time to ponder how japanese ladies are able to give birth and within two weeks look as thin as ever. Anyone know how they do it? Somebody should write a book and send the message to the world.
