For the true hero, the rescue is not just a noble deed, but an art form. And like any art form, it requires a deep understanding of the subtleties of pressure application.
The key to a successful rescue is applying the right amount of pressure. Too little, and the victim will slip right through your grasp. Too much, and you'll end up with a lawsuit.
Subtle maneuvering is key to avoiding the pitfalls of over- or under-pressure. Practice makes perfect, but practice with a partner, preferably someone who is not actually trapped.
