I have had a fair amount of training in practical methods of unarmed defense. I am fifty nine. I am 6'2" and around 220 and not all fat so I'm not helpless. I would not engage in a punching match with anybody. Any skills I have would be used for escape, weapon retention and to get sombody off of me enough to use an equalizer. I do carry a kuboton and OC so I am not in the position to have either the gun or begging for mercy as my only choices. I consider good social skills and self-control as part of my defensive package...So, it really doesn't take a lot of training to learn to use a few techniques that can help if the attacker is able to get close enough to negate using the gun. I taught a few of those things to staff who worked in psychiatric settings. All sorts of people were able to learn those techniques. Some modicum of practice is also a good idea.
