against a Great White.. Its true that you can survive a Great White attack.. you can be in the jaws of a Great White and punch him in th eye or in the nose and he may release you and swim away, so you've won the battle..
But.. its the 40 pounds of flesh and/or limbs you just lost in doing so.. ..and you may bleed out before you ever hit the beach.. So, you hafta decide what winning that war actually means..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
