Continuing the concepts that "usually" hold true, let's look again at this one:
"If your opponent touches or grabs you - they have one less weapon in play than you do."

There are multitudes of strikes that are safe for a woman to employ that won't hurt, while inflicting tremendous pain on an assailant.
Back with more, very soon!
