Genetics determines most of how tall children will grow as adults, but environmental factors affect it too. As the wealth of many countries around the world has increased over the past 100 years, living conditions and access to nutrition have improved and people have gotten taller.
A century ago, humans were quite short. For example, the average South Korean woman was about 4-foot-7, or 142 centimeters, while the average American woman was about 5-foot-2, or 159 centimeters. Humans were fairly short by today's standards, and that was true throughout nearly all of human history.
But in the past century, human heights have skyrocketed. Globally, humans grew about 3 inches on average, but in South Korea, women grew an astounding 8 inches and men grew 6 inches.
South Korea is almost unique in how quickly their population has gotten taller because they went from a relatively low-income country in the 1950s to well on their way to being a rich, industrialized country by the 90s. And the difference is particularly stark when you compare the heights of South Koreans with those of North Koreans, where the living standard is much lower and access to nutrition is restricted.
I really like the show-your-work vibe of this video, along with this recent one on the greatest unexpected performances in the NBA. These videos are not only relating something interesting to the audience, they're showing us how the data analysis works: where the data is from, how it's analyzed, and what it all means, which builds data and statistical literacy in a society that desperately needs it.
South Korea currently has a probe called Danuri orbiting the Moon at an altitude of about 62 miles above the surface. It's just begun its mission but has already sent back some black & white photos of the Moon and the Earth, including the two above. Over at EarthSky, Dave Adalian says these shots "rival the work of legendary nature photographer Ansel Adams" and it's difficult to disagree.
Always great to check back in on the work of Me Kyeoung Lee, who has been drawing delicate & detailed portraits of convenience stores from around Korea. Check out her Instagram for more work and some behind-the-scenes — I was surprised at how large some of her drawings are. (via colossal)
Oh, I really like these. The detail, the delicate realism, the muted but also somehow vibrant colors. Me Kyeoung Lee has been drawing South Korean convenience stores for the past two decades. There appears to be a recent book of her work, but I don't know if or where it's available (Google Translate isn't working on that page). Doesn't look like prints are available either. Yo 20x200, get on this! (via colossal)
Sales of CJ Corporation's snack sausages are on the increase in South Korea because of the cold weather; they are useful as a meat stylus for those who don't want to take off their gloves to use their iPhones.
Update: More than one person has suggested that this whole thing is a hoax. Video or it didn't happen? Feast thine eyes on someone playing a rhythm game on the iPhone with two of the meat sticks in question:
