Kim Jong Un (Kim Jong Il's son) is 29. Kim Il Sung Was 36 When He Took Over North Korea
Kim Il Sung's reign lasted 46 years.
Kim Jong Il's reign only lasted 17 years.
With Kim Jong Un becoming leader at the young age of 29, it means the North Koreans are likely in for another 50 plus years of Communist hell.
So when the rest of the world is flying around in hover cars, living in colonies on Mars and watching holographic television piped into their minds via telepathic internet connections, walking skeletons called North Koreans will still be eating tree bark and roots from any stray grass they can find and living in the cold darkness above the 38th parallel.
