I don’t train MA for self defense or to win a UFC or to become a Jedi Knight. I just train because I enjoy it.
If you wake up to find some lunatic holding a gun on your kid ordering your wife to tie you up, MA won’t help you. If you don’t train like a combat athlete, UFC gold will escape you. And midiclorians are in scant enough supply these days, outside of video games.
But having fun, getting some exercise, enjoying some social interaction – priceless.
