No, this is not about a magazine about self-defence, but self-defence using a magazine.
I remembered a story about my friend, he was with his girlfriend at that time on a bus and a guy in front of them kept looking back to catch a glimpse of his chick, ignoring my friend who was seated beside her.
So when it was their stop, he rolled up the news in his hand and as they passed the guy, he whacked the guy’s head and proceeded to get off the bus. The guy was so shocked he just sat there kept quiet. True story.
