Google cofounder Sergey Brin has popped his blogging cherry , using his first post as an excuse to promote his wife Anne Wojcicki's personal genetic testing company 23andMe . Turns out Brin has a genetic mutation likely inherited from his mother that indicates a higher risk for Parkinson's Disease — a debilitating condition that affects movement, resulting in tremors and eventual paralysis. Which would certainly be a terrible fate for a gymnast who loves kite-surfing. Brin has "decades to prepare for it," though. My suggestion?Brin should do what many in the health-obsessed Valley unilaterally shun: Take up smoking, as nicotine has been shown to have a prophylactic effect on the degeneration of dopamine-producing brain cells in mice.
