What about the person who passed the virus on to your colleague, the one before him and others earlier still? Contagious diseases operate like a giant infectious network, spreading like the latest YouTube clip among friends of friends online. We're social animals; we share. (See the Year in Health, from...

But Mugabe’s network of corruption was too strong to let that happen. After a slew of election recounts, much posturing, and, no doubt, vast amounts of behind-the-scenes violence and threats, Tsvangirai was essentially forced to withdraw from the election.
