Sergey Brin Launches A Personal Blog, Talks About His Risk Of Parkinson's

Google Cofounder Sergey Brin launched a personal blog today at

In his first blog post, he explains the blog name: “Welcome to my personal blog. While Google is a play on googol, too is a play on the much smaller number – two. It also means “in addition”, as this blog reflects my life outside of work.”

In the second blog post, he gets a little more serious. He talks about how DNA startup 23andMe (cofounded by his wife Anne Wojcicki) has shown he has certain gene mutation that is tied to Parkinson’s Disease – G2019S. While the mutation is rare in people with Parksinson’s, in some ethnic groups it accounts for a substantial proportion of familial Parkinson’s. In other words, if you have it, there’s a good chance you’ll get Parkinson’s.

He says based on current available data he’s 20%-80% likely to get the disease. And he can now do something about it:

This leaves me in a rather unique position. I know early in my life something I am substantially predisposed to. I now have the opportunity to adjust my life to reduce those odds (e.g. there is evidence that exercise may be protective against Parkinson’s). I also have the opportunity to perform and support research into this disease long before it may affect me. And, regardless of my own health it can help my family members as well as others.

I feel fortunate to be in this position. Until the fountain of youth is discovered, all of us will have some conditions in our old age only we don’t know what they will be. I have a better guess than almost anyone else for what ills may be mine — and I have decades to prepare for it.
