I'm not talking about baby taps and dead arms and stuff here, but real blows with the intent to cause damage. Personally I find it a difficult thing to do, though I have thrown a few in my life. Each time I was really enraged and lost control of myself. I've never thrown a punch in defense, or even desperation. My rational mind just won't allow it.
