security guard

If you're asking for your body, see the movie "the bodyguard". If you're asking for your store seethe fact that you will never be robbed, or you will never have your vitrine broken down. If you're asking for your house, you just minimize the case of being robbed and feel unsecure within your house. It's an awful feeling.

ammm..is that a trick question? the benefit is that he will protect ur store or whatever
