First of all, we have a lot of places where you can practice them in the netherlands, soo, it's very likely that there's a place not far from your home. It's also suprisingly fun! The people that you're training with (in my experience) are really nice, and fun to hang out with! And, it doesn't get repetetive!
There are SOO MANY ways to get your ass kicked (Disclaimer: People don't actually kick or hurt each other. Some of the positions you're forced in maybe unpleasant, but they're not supposed to hurt, and almost never do) in Ju-Jitsu that you've got quite a few years to go before you've experienced them all.
And, you're also learning stuff, wich is why I personally like it soo much! The sport is defined by growing! Experiencing new ways "to get your ass kicked" learning to see them coming, and effectively stop them, and at some point even succesfully taking down an oponent, and "kicking his ass" instead! I think it's just really satisfying to feel like you've learnt new stuff, and got more proficient every training day.
And, ofcourse, it's actually usefull outside of the sport aswell!
Because, if someone does something to you, for whatever reason, be it pesky narcistic older siblings, trying to steal your lunch, or bigger classmates/strangers just being assholes, or worse, trying to mug/attack you, you simply know how to handle those situations better, because that's what you're training with, every week!
And, most importantly of all, (and also the most overlooked/underrated) it boosts your self-confidence big time!
This is actually something that most people don't believe matters, but I've seen it with my own eyes. The whole way that you are trained also includes your stance, and attitude. They'll also train you to stand more firmly, making you harder to push around, and even scarier to people thinking of doing so. Really... People take that attitude home and into their daily life, and it somehow just makes them a lot more confident in themselves, and that confidence alone seems to be enough for the people I train with to scare off bullies, or assholes!
Yeah... Needless to say, I really think a martial art would be a good idea! Specifically Ju-Jitsu, because it's aimed much more at the pure self-defense purpose, teaching you all the dirty tricks, and skipping the useless stuff, like Karate's "dance moves" that don't really do anything...
