Some good points here, but the bottom line is that anyone can improve their self-defense skills and fitness, (unless you are the world champion reading this).

Most men, (~90%?), have never hit another person in their life. Or at least since grade school. When you go into the rougher neighborhoods or a nightclub full of macho alpha-dog types, the percentage might be a little higher, but still you would be surprised how many "tough guys" have no real skills. If they are not totally dominating or knocking someone weaker than them out w/ one punch, they run out of skills in a hurry. I worked for quite a while in nightclubs, including the door, and I've seen more fights and blood than I ever wanted to. I've seen tiny guys, (150 lbs.), completely frustrate the schit out of 220 lb. muscle ****** "tough guys", if not outright kick their asses. And I've just seen horribly dirty fighting, 2/3/4 on one, etc...

You could do a lot worse than Krav Magna, IMO, and anything that improves fitness, health and confidence is a positive thing. Even if it's kicking a soccer ball around.
