What is the difference between self-defense, realistic fighting and dueling (sports fighting)? part 1英語版

日本語今度書きます。英語の文章。Part 1
I often get asked questions about self-defense versus sports fighting (格闘技 in Japanese) so I decided to write down how I define self-defense, realistic fighting and sports fighting. I feel many people are confusing the different terms and end up not realizing what they are actually learning. I'm starting with a few thoughts on self-defense, with more to be added hopefully soon.

​Self-defense
What self-defense should be like: Teaching of the simplest and best techniques for dealing with the most common attacks and teaching of the mental preparation needed to handle the stress of such situations.
Self-defense should be taught as a limited course to quickly equip the person with the most basic skills to handle a situation and get away safely. Think of it as learning self-defense first aid: you learn just enough to deal with the most common attacks and get away.

What it often is taught like: Teaching of techniques to defend attacks that are not likely to happen, techniques and tricks that are of very little value out in the real world, and no mental preparation on how to deal with a real situation.

Real self-defense is more than just a technique. It's also about what happens before and after you get into a situation where defending yourself is needed.
Without mental tactics many people will just freeze when they come upon a dangerous situation. So what happens before is important.
Just applying a technique to free yourself might not be enough. What will the attacker do next if you stop there?
Sometimes simply running away isn't that easy. What if you are in an apartment, elevator, public toilet or a similar confined space? The techniques to free yourself are just a little part of self-defense curriculum.
