Advoid dark alleys, step softly, keep your eyes down, but be like a coiled spring;
When they feel you are not a threat, strike, strike, and strike again, don't give up, shatter bones, rip out eyes, rupture ear drums, smash testicals, stomp on the top of the foot to break bones, pick up the heaviest object you can swing and attack, attack, attack...
No normal man wants to fight, but if the fight is unadvoidable, be ready to kill!
Will you survive?
I don't know, each man faces their own mortality, perhaps if it is destined for you, you can leave the world a little cleaner...take out the garbage, turn off the lights!
