In that case, you'd probably also want to bet that we all wear short sleeves at all times when working on a pc, and I personally don't always do that. All the machines I have here are towers, and I don't want to go through the hassle of fully unplugging them just to work in them, so I work with the tower cases standing like they normally would, which means my elbows are usually on the ground. Even if working on a desktop, most of the time, I work on those with the machine facing me, like it normally does, which means that even if you do lean an arm on the chassis, usually the bulk of your arm is actually in contact with the plastic on the front of the chassis, and not with the metal frame. You also want to be in contact with an unpainted metal part of the chassis, (the best place is usually the outside of the power supply at the back of the chassis), since painted metal surfaces don't do the job. Personally, if I'm doing something quick and dirty, such as swapping cards in and out, I'll touch the back of the case with 1 hand, while working with the other. If I'm doing anything major though, especially if I need both hands inside, I do use a wrist strap. After all, it takes very little static electricity (which you might not even feel), to destroy 1 or more components.
