Being an oldster (74 yrs old) I don't plan on letting anyone hit me whether it's a confrontation in a store or a parking lot. I know that pulling my pistol is a last resort but if I am forced to shoot someone for jerking me around, pushing or trying to punch me hopefully my age would be taken into consideration even if the aggressor has nothing but his fists and feet. I think it's safe to say that a punch to my chest or head could cause grave injury or even death. Your expert opinions please.
