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.
