Paintball is a growing sport (its #3 extreme sport played in USA according to Paintball Magazine), by many not really regarded as a sport (the fools!), and really given bad spin by media which make it to be trigger happy prep school for terrorists, gang members, and sociopaths. But its more!, its an expirience beyond anything else. Its a super un-discriminative sport. It can be played by people with uncany mind and great body or none of those, not always in the same package. Its where size does not matter, its where sheer strenght does not matter but can bring advantage or downfall, its how you think its how you play who you play with, and what you play with. Your equipment can be your victory or your defeat, it is where you controll all variables and where you don't know what you control untill it starts. Its an adrenaline pumping mind streaching body burning expirience. Feared by parents all over the world! Its a better drug!
