cauliflower ear

Question
ive been wrestling for couple years now and have yet to get cauliflower ear, but i really dont want to get it. I dont use headgear and practice, only in real matches. Do I really need to start using headgear? Like what are the chance i would get it if i dont use headgear?

Answer
That just depends on how dirty your mats are. Such as do you mop it before and after practice with a cleaning agent? Do you have to take off your shoes before entering the mat? If the answers are no then your chances of getting cauliflower ear is high. It's pretty common too so I would say you should start using your headgear unless you want your ear to be drained. Also, if you have a protective foam that you put on before you practice, it would help as well to prevent it. Your always taking a chance without using headgear.
