Hey guys, having fun and improving ourselves can both be the purpose for sparring.You wrote have fun, but the way I read what you wrote was that improving yourself is the purpose, and having fun was a side effect. To me, having fun is the purpose, and improving myself is the side effect.
Side effects may include bruises, sore muscles, pulled muscles, strains, sprains, bloody noses, broken bones, concussions, gasping for air, exhaustion, spontaneous combustion*, embarrassment, temporary euphoria from feeling like a badass, and discouragement from being reminded that you aren't nearly as badass as you had previously imagined. Ask your doctor if sparring is right for you.
*(Primarily for practitioners of Kabumei. Occurs in less than .02% of sparring sessions for other martial arts.)
