The thought that concerns (and actually saddens me… just a little) is that if one cannot tighten a simple screw with a calm demeanor and clear head, how would one cope with an actual emergency situation? Survival involves a lot of improvisation. You will probably have to tighten many screws along the way. You cannot get a refund if you are dead.
