About to get into a fight, any tips?

Punch your hand. Now get a standard bic lighter and punch your hand. Notice the difference. Punching with a lighter in your hand keeps the bones inside straight, reducing pain and risk of injury. It thus allows you to punch harder. Also don't be afraid to kick them in the balls, jab at their throat or eyes, or twist their limbs. Hit them with a rock or whatever else you can find. There's no such thing as a fair fight
