My wifes a nurse and has had a few in real life catfights. Sadly the last one she got bottled over the head,after she had been attacked from behind.she had a pre arranged fight with another nurse she works with once,but all they really did was pull hair,but at least nobody got badly injured.
My wife will play wrestle with me sometimes and she does know how to squeeze muscles and it can hurt.Love it (and her) though.
Fights between nurses,away from work obviously are not uncommon.they get stressed with each other due to the pressure of the job.My wife though has only ever had the one,and theyre friendly again now,so i doubt much chance of a rematch.Pity cos it was quite a turn on having my wife fight in our living room,loads of hairpulling and no one getting badly injured.
