Today in history: Bajillionaire mayor of Silicon Valley Mark Zuckerberg turns 28 years old. And just days before Facebook is expected to go public.

While you're reeling about in a constant state of financial panic, wondering how you're going to pay rent on your next drafty 2-bedroom in some outer district of San Francisco, try not to think too hard about how Zuckerberg could spend $300,000 per day until he was 80 years old and still have money to comfortably live out his twilight years.

Seriously, it's a wonder that guy even bothers to show up for work anymore.
