Not fer nutin', because I agree that it's fake, but wearing a helmet doesn't make taking a good shot to the melon painless.
Oh certainly, but those "kicks" would have been ineffectual without a helmet.
I worry about my daughter -- she's 5'2", about 115 lbs and very cute! She did briefly take Krav Maga, but doubt she got much from it besides bruises.
I was choked unconscious by a smaller woman that that in a BJJ class. She had 2-3 years in, very difficult to deal with, like juggling snakes. Of course, I'm a n00b, but still.
