But men love fighting, many are involved in either boxing, muay thai, wrestling etc. It's very uncommon for a female to be involved in any type of martial arts. Where I grew up, there were plenty of girls playing basketball, volleyball and tennis, and I never heard of any women in any sort of combat related sport, while at least 10-20% of males that train sports are in some martial art that can later merge into MMA. Ratio of men to women in basketball is 10:1, while in martial arts it's at least 100:1
