Yeah. And I say that as someone who has little interesting in actually going to train boxing and wrestling.
I enjoy the historical, artistic, philosophical and sport elements of martial arts in addition to just the raw fighting element, and I have gravitated more toward karate and taekwondo and judo.
But yeah, if you just want to learn how to go beat a dude's ass and you want to pick these skills up as quickly as possible, go do boxing and wrestling for a year and you'll probably be ready to handle most untrained dudes you run across on the street, provided you're not way outsized.
