Are North Koreans really three inches shorter than South Koreans? By Richard Knight BBC News It's often been reported that North Koreans are a few inches shorter than their counterparts south of the border. Is that true? North Korea's recent failure to launch a long-range rocket was embarrassing for its new leader, Kim Jong-un. It was supposed to be a symbol of progress. Renewed media interest in North Korea since Kim Jong-un replaced his father has prompted the re-emergence of a claim which appears to be a symbol not of progress, but of relative decline: that North Koreans are much shorter than South Koreans. The Independent reported last week that "nothing is small in North Korea apart from the people, who are on average three inches shorter than their cousins in the South". This statistic, or versions of it, have been quoted for some time. In 2010 the late Christopher Hitchens put the difference

By Michelle Roberts Health reporter, BBC News   Completing 26 miles of physical endurance can take its toll Running a marathon puts immense strain on the body.

Spam: India leads world in junk emails   Many spammers have shifted their focus from email to social networks India has become the top spam-spewing nation on the planet, suggests a report. Compiled by security firm Sophos, the report ranks nations by the amount of junk mail routed through computers in each country. India has leapt to the top of the spam chart in less than a year, rapidly overtaking the US, said Sophos. About 10% of all junk mail sent across the web came from or passed through computers in India, said the firm. India's rapid rise up the chart of spam producers has been helped by the rapid growth of the web in the country, said Graham Cluley, senior technology consultant at Sophos. The inexperience of the many first-time net users in India had led many to fall victim to hi-tech criminals, he said.
