Why are lawyers always referring to "personal" injuries? Aren't all injuries "personal?"

In the law, the word "injury" is a broad term that can have mutiple meanings.  Depending on the case, an "injury" can refer to damage caused to a person's body (such as a herniated disc in the spine) or it can refer to an injury to property (such as damage to a vehicle, home or business.)  Because there are different laws that apply when the damage is to a person's body, lawers are usually careful to specify whether an injury is "personal" (meaning an injury to a person's body) or whether the injury is to a person's property.  To the lawyers, saying "personal injury" makes perfect sense because it explaines the body of law they apply, but to the general public, the term can be confusing.
