Must be nice to have 29m of "just" living expenses.
$1.7M in living expenses, not $29M.
Still a lot, but a house in Palo Alto and personal security alone might justify most of that. Guys like Steve Jobs who take $1 in salary already have lots of liquidity, and Zuckerberg doesn't necessarily have that.
He has facebook pay for his security detail and private aviation... like a boss.
