what the **** are you talking about?
Idk, it just seems like all the guys at martial arts class are really ugly dudes, so one could only assume they're trying to put martial arts on their resume for conversations.
I'm not saying that's you or that you're definitly ugly, LOLOL...
But martial arts in this day and age.. Not a very efficient form of exercise.. and defending oneself is impractical, because you're better off handing over your wallet // phone
Even assuming you COULD defeat your mugger with martial arts,,, the time + resources expended to learn it will never equal the amount a mugger would take from you.
So say it's $30 a lesson, you go once a week, become proficient in 2 years. that's $360
Then there's extra food that you eat due to extra calories burned during practice.
A mugger would take from you at most your phone, $200, a wallet, another $200
You're honestly better off just giving him the stuff,, NOT have to practice anything,, and the diminished aggression during the exchange is FAR FAR safer than a fight, EVEN if you are likely going to win.
