What are Sergey Brin and Larry Page really obsessed about? Look no further than their choice in lifemates, says Attila Csordas. Sergey Brin married 23andMe cofounder Anne Wojcicki — and also lent the company $2.6 million, which Google repaid when it invested $3.9 million in the company. Larry Page's fiancée, Lucy Southworth, is close to earning her Ph.D. — a feat neither Page nor Brin has accomplished. Her field of study is biomedical informatics, a field which harnesses high-powered computing for biotech research. Larry and Sergey made their billions on online advertising, a business the pair openly despised when they created the Google search engine. The heart has its own code, and in Larry and Sergey's case, I think it's DNA base pairs.
