As an add on to my notes yesterday (and all warnings still apply) . If someone grabs a hold of you and you still have one hand free keep this in mind. If you rub your knuckles back and forth across the back of their hand or if you strike the back of the hand with your knuckles (hard) it will probably get them to let go. This action is rather painful but should cause no permanent harm, a pressure point thing. . .
Give it a try on yourself, rub the back of your off hand with your other hands knuckles. You may note that the closer to the target's knuckles you rub the more it hurts. You do need to be able to apply some good pressure for it to work right. . .
And that is your tip for today. . . .
