1.Pinch and pull soft tissue on underside of the arm or inside thigh, followed with a closed fist back hand to the nose?----PINCH? Please--this might work f your attacker is 10. All you do is piss him off--actually, it is probably more amusing than anything.
2. Two fingers jabbing into the throat
--fill a bowl with sand--jab two fingers into it--how did that feel?--never hit anything with your fingers unless you've been doing it for years
3. If grabbed from behind, bend forward to make it harder for the guy to hold on to you
...sorry for this one---imagine the new position--HE WANTS YOU BENT OVER! Bending over leaves you totally vulnerable
4. Yell at the guy like a stark raving mad, crazed person. Calling attention to the situation may cause him to back off
--A good option, but be ready for him to "Shut you up"
5. Never get in the car with the guy. You're already dead if you do.
--True
6. Don't bother a kick to the groin. He will expect it and you'll end up on your butt
...True
7. Carry peppper spray and use it on him before he gets to you (of course, he was selling said pepper spray)
A good option but hard to use unless you have it in hand and have practised (read, buy two use one to practise--be prepared for the sting when you get it on yourself
I suggest "The Gift of FEar" an excellent book---
