I must have missed the announcement, but this has to be a large joke right? The amount of shit that will get people killed on here is just constantly being repeated, telling small women how to train to fight off multiple opponents with their fists, people recommending carrying tactical tomahawks, others suggesting to just keep beating people after they are unconscious.
Its like somebody just brought a voice recorder to a literal mall ninja shop and turned it into a text transcript for reddit.
If anyone's wondering, the first rule of self-defense is to avoid a physical conflict. The second is to run away. The third is that if you're being held, brutally apply enough sudden pain that you can get free and run away. That last one doesn't always work which is why you do the first two if you can.
If you're resigned to fighting, you could very well die. It's not like the movies where you take punches and fall over and everything is fine. Fall wrong and hit your head and you're dead/paralyzed. You could get kicked on the head, which is rightfully considered an attempted murder because likelihood of death is high. This is why so much of martial arts is about keeping your footing, stamina, and protecting your head.
If you take a self-defense class and the first few courses aren't about avoiding conflict, it's a bad class that will probably teach you some bad habits.
