What I learned after 20 years of combat training in a dojo (full body fights) is that 3 seconds of inattention and my 4 years old son kicked me in my testicles after missing the ball. It is a miracle he now has a brother.

#4 is great, your ability to run a 400 meters in 70 s is awesome too.

Do not get into fights if there is any way to avoid them (including begging).

I you have to fight to full throttle and be the one to hit first.
