Matt Cutts wrote that Sergey Brin have got a blog. Sergey told that this blog dedicated to his life “outside of work” – actually there’s only one post about 23andMe – project founded by Sergey and his wife Anne Wojcicki. In 23andMe blog Sergey ( and other 23andMe founders ) tried to explain why DNA research is so important for everyone, and how it can help people to struggle with diseases. I’m sure that projects like 23andMe are very important for human health, at least, because the knowledge is power.
