My mom thought it was a good idea for us to take a self defense class. It was four hours long, and we didn’t learn any flips, kicks, or other fighting moves seen in movies. That, according to the teacher, was not self defense.
We covered a lot of ground in a short amount of time: How to get out of chokes (from the front and behind), how to stand and fall without hurting ourselves, how to survive being attacked by a dog, etc.
I hope that I never have to use any of the techniques but it’s better to be safe than sorry.
