I'm 73, a master instructor at karate. I'm retired and I seek a motivated, disciplined male student to pass on my knowledge. call or text 580-507-6444. Lawton, OK area. You have to be willing and able to train hard 1 hour per day, 6 days per week, for the better part of a year. If you will do this, I will make you untouchable by any un-trained man, if you are aware of the attack, if there's only one attacker, if there are no weapons involved. You can learn to handle multiple attackers, weapons, maybe even being surprised in awkward positions, but that will require yet another year of training.
