Physical Danger
If you screw up an A-lister's face, or drop the ball on a powerful politician's lift, you could be in serious danger. You might have to deal with a celebrity's angry entourage or a freaky fan who doesn't appreciate your handiwork. It wouldn't hurt to take up Tai Kwon Do or work some MMA moves into your workout routine, just in case.
Still, bodyguards aren't de rigueur in 90210, so don't sweat it too much.
