I've been perusing this channel for a while and I like these guys. Mark Phillips is a Wing Chun practitioner out of UK and on some of his vids he does reality fight analysis. I remember years ago I was given an in-service training class on pre-fight cues to help us in confrontations with angry, non compliant individuals. Things like clenching the fists, looking away and other less obvious ones such as brushing the hair back wiping the mouth etc. often happen before people let loose on you. This video is a good example of just that. And Happy New Year to all Kung Fu Brothers and Sisters!
