LONDON, ENGLAND - MARCH 15: People work at computers in TechHub, an office space for technology start-up entrepreneurs, near the Old Street roundabout in Shoreditch which has been dubbed 'Silicon Roundabout' due to the number of technology companies operating from the area on March 15, 2011 in London, England. Entrepreneurs using TechHub are predominantly product-oriented tech companies who rent desk space and use the fast wifi. The relatively low rental rates and proximity to media and internet companies has made the area close to the roundabout a prime location for IT firms and web entrepreneurs.

BERLIN, GERMANY - SEPTEMBER 05: A doctor speaks with a patient about her high blood pressure, or hypertension, on September 5, 2012 in Berlin, Germany. Doctors in the country are demanding higher payments from health insurance companies (Krankenkassen). Over 20 doctors' associations are expected to hold a vote this week over possible strikes and temporary closings of their practices if assurances that a requested additional annual increase of 3.5 billion euros (4,390,475,550 USD) in payments are not provided. The Kassenaerztlichen Bundesvereinigung (KBV), the National Association of Statutory Health Insurance Physicians, unexpectedly broke off talks with the health insurance companies on Monday.
