Actually, that leads me on to a completely unrelated topic... I'd always wondered why Koreans (and Asians in general) have always been so physically inferior to the rest of the world in terms of height and size, and I think it all comes down to nutrition (well, in Korea's case anyway).
We've a rich and proud history of war, and being occupied and bullied by all of our neighouring nations, meaning that the past __ generations of Koreans up until now grew up in poverty and malnutrition.
Now that living standards have dramatically increased in Korea, I see more and more that the general populous is taller, bigger and healthier than generations past.
The reason I actually got thinking about this is that I was wondering why it's only recently that Asian athletes have started making any kind of impact on the world stage, and I'm pretty certain it's along the same line of reasoning.
